[[http://www.nitrome.com/ Nitrome]] is an independent game developer known for its Flash games, many of which are on Miniclip. Nitrome's games often have highly unusual gameplay that forces the player to think ''well'' outside the box.

----
!!Nitrome's games contain examples of:
* AbsurdlyHighStakesGame: "Flipside" is a fun racing game... [[spoiler: that determines whether the protagonist stays in prison or not.]]
* AdvancingBossOfDoom: Present in both "Ribbit" (as a hybrid of a rhinoceros and a beetle) and "Off the Rails" (as a train.) The final level of the latter has two such bosses, one in front of you and one behind, preventing you from going too fast or too slow [[spoiler:unless you do a jump and manage to get over it, in which case you can reach the level's end quickly and without impediment.]]
* AdvancingWallOfDoom: "Avalanche" has a straight one. "Cave Chaos" uses an odd variant: the scenery constantly assembles in front of you and disassembles behind you, forcing you to keep up or fall to your doom. "Super Treadmill" takes place on a treadmill, and you lose if you fall off either side.
* AffectionateParody: ''[[SuperMarioBros Happy Jump Land]]'' in "Enemy 585".
** In "Mega Mash", There's a game called ''[[VideoGame/{{Tetris}} Nitrometris]]''.
* AfterTheEnd: "Rustyard," starring a robot that wanders the ruins in search of places to recharge its batteries.
** The second game in the "Toxic" series takes place in a world where the robots took over.
* AllThereInTheManual: Some of the plots are only mentioned in the game descriptions.
* AlwaysABiggerFish: In "Cheese Dreams", [[spoiler: the ending has you escaping the ship... [[ShootTheShaggyDog only for you and the ship to be promptly eaten by a ship shaped like a cat.]]]]
* AnIcePerson: "Jack Frost".
** Also Bad Ice Cream and its sequel.
*** And the sequel to that as well.
* AmusementParkOfDoom: "Skywire".
* AntiHero: Often, the people who are fighting you are perfectly reasonable, such as in "Worm Food", when you're terrorizing [[MakesJustAsMuchSenseInContext floating islands]] with people living on them simply for food.
* ArmlessBiped: The [[AllTrollsAreDifferent troll]] protagonist of "Square Meal".
** Also the titular character of "Lockehorn" and his tribe.
* ArsonMurderAndJaywalking: From "Tiny Castle": "[...]And also subletting to your grandad was the final straw!"
* AWinnerIsYou: Rarely, but "Bullethead" stands out in this regard.
* BadassAdorable: Hot Air Jr. from... [[CharacterTitle guess!]]
** Also, Left Eye from "Colorblind".
** The main characters in "Twin Shot". Kittens! [[ArcherArchetype Kittens with bows]] [[LikeABadassOutOfHell that destroyed hell!]]
* BadBoss: The BigBad of "Office Trap". He forces prospective employees to make their way through an office building riddled with death traps and agrees to give a temporary work contract to all the survivors.
* BeYourself: By Day 17 of "Super Treadmill", Billy no longer cares about his weight or the competition, and if he decides to lose it, he'd rather eat healthy and exercise than use the Super Treadmill. Of course, his Uncle Rico is hell-bent on making Billy lose weight on the treadmill...
* BizarrePuzzleGame: Pretty much all of them, with "Flipside" being a notable exception.
* BlackKnight: The protagonist of "Tiny Castle", at least in terms of how he dresses.
* BlackSheepHit: One of their most popular games is "Mutiny", which is a lot simpler in gameplay to most Nitrome games; although it looks like a Nitrome game in terms of design, it's one of their few games with no BizarrePuzzleGame elements.
* BloodlessCarnage: So far, only "Graveyard Shift" and "Parasite" have used blood at all, and in those it's been greenish gunk. "Nitrome Must Die" also uses blood, and its color varies depending on the enemy.
** Well, there's a bit of normal, red blood in the vampire level of Pixel Pop.
* BossGame: SkySerpents.
* BrilliantButLazy: The main character of "Glassworks".
* BullfightBoss: The final level of "Super Treadmill".
* CallBack: "Nitrome Must Die" and "Super Stock Take" are made of them.
** In "Small Fry", it's difficult to see, but in the background, you can see the protagonist of "Cheese Dreams" sitting in the sky.
* TheCameo: So many of them.
** EarlyBirdCameo: The zombies, plant, and maiden from "Graveyard Shift" debuted months before the game was released.
* CartoonCheese: The protagonist of "Cheese Dreams" is made of it.
* CatsAreMean: "Doghouse"
* ChainedHeat: Necessitates your awkward movements in "Knuckleheads."
* CharacterNameAndTheNounPhrase: "Dirk Valentine and the Fortress of Steam"
* CharacterTitle: "Enemy 585"
* ColossusClimb: "SkySerpents".
* ComicallyMissingThePoint: If "Skywire VIP" is any indication, people were more interested in the little people that you drive around in "Skywire" than the actual gameplay.
* ContinuityCavalcade: [[MilestoneCelebration "Nitrome Must Die"]] is loaded with characters from previous games.
* CoolTank: "Steamlands" in a nutshell.
* CorruptCorporateExecutive: Your leader in "Castle Corp." He may also be a PointyHairedBoss, considering how cliche his idea of a pep talk is.
** The FinalBoss of "Nitrome Must Die", who also appears in "Super Stock Take".
* CraniumRide: The title character of "Parasite" uses a particularly brutal version, burrowing its tentacles into the heads of foes to control them and use their abilities. Creatures so controlled get a SicklyGreenGlow [[GlowingEyesOfDoom in their eyes]] and [[{{Phlegmings}} a constant stream of green drool]], and when abandoned explode into LudicrousGibs.
* CrosshairAware: "Final Ninja."
* {{Cyberpunk}}: "Final Ninja" has a lot of elements of the genre.
* DamselInDistress: Referred to as such in "Graveyard Shift". You've got a HostageSpiritLink to them, and they die in a single hit from a zombie, so be careful.
* DeathIsASlapOnTheWrist: "Fault Line". You're merely sent back to the last checkpoint you accessed, and any fastened fault nodes that hid it are unfastened.
* DeliberatelyMonochrome: Each level of "Yin Yang" is essentially two in one: one that's on a white background, with everything in black, and one that's on a black background, with everything in white. Everything that's empty air in one world is a solid block in the other. The two main characters can't directly interact, but can sometimes move crates around to open up holes in the other character's landscape.
* DemBones: Seen in "Small Fry", "Mutiny", and "Numbskull".
* DifficultySpike: Practically their SignatureStyle. The first five to eight levels will be pretty easy tutorial levels, but then things get ''crazy''. Averted by some games, though, like Tiny Castle (it's just one level) and Blast RPG (the level system is a bit different).
* DroppedABridgeOnHim: Used on zombies in "Graveyard Shift"... Oh, wait, you were using the phrase ''[[LiteralMetaphor metaphorically]]''?
* DropTheHammer: What happens if ice (or an unfortunate monster) lands on the ship's deck in "Ice Breaker".
* EldritchAbomination: The player character in "Worm Food".
* EliminationPlatformer: ''Twin Shot'' and ''Twin Shot 2''.
* EscortMission: The owl in "Fat Cat" functions rather like a standard plane in a standard shmup, but is completely ImmuneToBullets. The cat is slow and vulnerable, but must be kept alive so that it can [[WaveMotionGun smash down walls the owl can't damage.]] In later levels, this means deliberately moving the owl into [[BulletHell hails of bullets]] to keep them from reaching the cat.
** ''Enemy 585'' is all about escorting a slow, fat {{mook}} escape.
* EveryCarIsAPinto: Even if it's a hand-powered trolley car, as seen in "Off the Rails".
* EverythingsBetterWithPenguins: A penguin is the protagonist in "Avalanche". "Snow Drift", however, has penguins with an almost identical design as antagonists.
* EverythingsBetterWithRainbows: :Rainbogeddon"
* EverythingsWorseWithBees: Both "Skywire" and "Nitrome Must Die" has them as antagonists.
* EvilLaugh: The protagonist of "Mirror Image" gives one every time he survives a level.
** The protagonist of "Parasite" also does this every once in a while.
* ExcusePlot: Very, very common. However, games that descend into PlotWhatPlot often have TheReveal at the end explaining what you've been doing the whole time.
* ExpansionPack: "Ice Breaker: The Red Clan" and "Ice Breaker: The Gathering".
* EyepatchOfPower: Both the title character in "Dirk Valentine" and Akuma in "Final Ninja Zero".
* FacelessGoons: "Castle Corp", "Double Edged", and "Dirk Valentine and the Fortress of Steam". Note that the former two also have faceless ''protagonists'' -- apparently, [[HelmetsAreHardlyHeroic helmets are sometimes antiheroic]].
* FakeDifficulty: Nitrome's specialty is to take things that would usually be considered such, particularly {{Interface Screw}}s, and try to make them reasonable and enjoyable limitations.
* FollowTheLeader: Many Nitrome games can be traced to an individual game they're copying (for instance, "Small Fry" is a mimic of ''VideoGame/{{Lemmings}}''.) To its credit, it's often quite inventive in creating new challenges within the same basic framework.
** The game sequels also tend to be exactly like additional levels of the original games. Notable exceptions include "Test Subject Arena" and "Skywire VIP", although there were individual sequels to "Skywire VIP" that fit their normal sequel formula.
* ForTheEvulz: The main character of "Parasite".
* {{Foreshadowing}}: In the background of ''Nitrome Must Die'', there's a whiteboard labeled 'New game ideas'. One of the ideas was a 'Game with blobs'. A month or two later, ''Swindler'' was released, in which the protagonist is a green blob.
* FungusHumongous: A common background element in "Small Fry".
** Also appears in the background of "Swindler".
* GoingCommando: Judging by the intro of "Toxic 2", the protagonist isn't wearing anything under that radiation suit.
* GoombaStomp: Your alternate attack in "Frost Bite." "Ribbit" is an interesting variation in that you can only do this if you've charged up for a high jump -- standard jumps just result in CollisionDamage.
* {{Gorn}}: "SkySerpents" has LOTS of ([[AlienBlood blue-ish]]) blood, especially when you win a level.
* GrapplingHookPistol: Your way of getting up the mountain in "Frost Bite," as well as your primary weapon.
* GravityScrew: "Rush" has as its gimmick the ability to flip your character from floor to ceiling, not unlike ''VideoGame/{{VVVVVV}}''. You can also flip your opponents' tracks, causing them to get screwed over as well!
** "Swindler" is based around being able to rotate rooms/levels.
* HaveANiceDeath: It's worthwhile to lose intentionally in "Mutiny" just to see the unique messages for every battle.
* HealingPotion: "Graveyard Shift". Somehow, it works by ''shooting'' it.
* HeKnowsAboutTimedHits: Usually, the necessary information is on signposts scattered around the level. "Cheese Dreams" gives these from the main character's perspective, with the inevitable [[LampshadeHanging lampshading]] of "Why are my thoughts appearing on these signs?"
* HourglassPlot: [[spoiler:The ending of ''Super Treadmill'' shows Billy having finally lost weight, while Uncle Rico becomes obese.]]
* HumanCannonball: "Blast RPG."
* HumanPopsicle: Your objective in "Ice Breaker" is to liberate them. [[HarmlessFreezing Don't worry, a good whack with a hammer and they'll be perfectly fine]].
* HundredPercentCompletion: There's a fuse in each level of "Rustyard," and several vials of acid in each level of "Toxic 2." In each case, you're encouraged to collect them all, though neither explains whether anything special happens if you do (a screen in the former says "Have you been collecting those fuses? What for?"). Of note is that these are among the few Nitrome games that have no leaderboard for ScoringPoints or completing a level in the smallest possible time.
* HuskyRusskie: One of the protagonists of "Rubble Trouble." He has a tendency to provide powerful explosives with only vague explanations of where he got them.
* HyperactiveMetabolism: Sushi in "Final Ninja" and a SpotOfTea in "Dirk Valentine".
* InterfaceScrew: "Super Treadmill" and supposedly its {{Spiritual Sequel}}s are based on old NES games, so Nitrome has put in occasional TV static and glitches into AV mode.
* InvisibleMonsters: The levitating swords in "Tiny Castle" aren't actually levitating -- they're held by invisible swordsmen, who flash when struck.
* JustToyingWithThem: Your SarcasticDevotee in "Toxic 2" is certain the robot leader is doing this -- you can't ''possibly'' have gotten this far without her wanting you to. It's never entirely clear whether he's right about this, though either way, a good player is being underestimated.
* KillerRabbit: [[spoiler: The final boss]] in "Hot Air Jr". No, really!
* KnightInShiningArmor: The protagonist of "Blast RPG", though he's [[KidHero a little young for the role]]. If his HP drops to zero, the armor breaks and shows off his GoofyPrintUnderwear as he [[OcularGushers cries a river of tears]].
** Subverted in "Tiny Castle". At first, it seems like this trope applies as you try to save a princess. [[spoiler: It turns out your were just evicting her.]]
* LeetLingo: A very mild example in "Super Stock Take" -- in the ending, the CorruptCorporateExecutive says two sentences (one of which, of course, being a BigWhat) filled with exclaimation points capped with an "11"
* LarynxDissonance: In Icebreaker.
* LastOfHisKind: "Final {{Ninja}}".
* LegionsOfHell: They wander the ruins in "Mirror Image". Don't get too close.
* LightningCanDoAnything: It revives a skeleton in "Numbskull".
** In "Headcase," it teleports the main character to "a world where everyone walked on walls" and turns him into a superhero.
* LuckilyMyShieldWillProtectMe: How you prevent zombie goop from killing you in "Graveyard Shift". Pieces break off it as it blocks more and more hits, but it never completely breaks, and you can replace it at some points.
* LudicrousGibs: "Graveyard Shift" and "Parasite" are straight examples. "Off the Rails" has gore, but no blood, with dead bodies splitting into neatly sliced bits resembling steaks. "Final Ninja" has no blood or gore, just body parts flying every which way in a [[GrotesqueCute disturbing]] [[UncannyValley fashion]].
* MadScientist: The villain of "Ribbit".
** Also, one created the protagonist of "Test Subject Blue". In "Test Subject Green", Blue is captured by a different mad scientist that created Greens to destroy him.
* MalevolentArchitecture: Lampshaded in "Final Ninja Zero", and present without acknowledgment in too many games to list.
* MilestoneCelebration: Their 100th game is about... some guys attacking them.
* MindRape: You perform them to different animals in "Parasite".
* MindScrew: "Tiny Castle" owes a ''lot'' to ''VideoGame/{{Braid}}'', at least until TheReveal.
* {{Minimalism}}: ''Gunbrick'', ''J-J-Jump'', ''Turnament'', and ''Ice Beak''. So much so, they are the size of the game thumbnails!
* MixAndMatchCritters: The {{Mook}}s in "Ribbit" are standard versions of this, like a snake with porcupine quills. The title character is a variant, with a rabbit's head and a frog's head joined by their necks, lacking a torso or limbs. (Note that Ribbit is ''not'' a MultipleHeadCase or TwoBeingsOneBody, referring to itself as "I.")
* MoneySpider: Lampshaded in "Tiny Castle" at the end--[[spoiler:the princess has so much money that she feeds it to the monsters]].
* MundaneMadeAwesome: Many, many games.
** "Pest Control" is exactly what it sounds like: you're an exterminator killing insects. And it's fucking ''awesome''.
** The "Frost Bite" series is about hiking, and "Thin Ice" is about ice skating.
* MyBrainIsBig: The protagonist of "Head Case". [[UseYourHead This has multiple applications]].
* NightOfTheLivingMooks: "Graveyard Shift".
* NoFourthWall: In "Skywire VIP" the hosts speak directly to you, ponder why you're not pressing the play button, and even [[RageAgainstTheAuthor insult the programmer]].
* OddNameOut: "changeType()" is the only game they have made which name starts with a lowercase letter.
* OneHitPointWonder: Applies in many of them, such as "Hot Air", "Hot Air 2", and "Parasite". Justified in the former two in that you're a hot air balloon.
* PacifistRun: You get bonus points for this in "Final Ninja." By "Final Ninja Zero" it's inverted: you get bonus points if you LeaveNoSurvivors.
* {{Pirate}}: All the main characters in "Mutiny."
* PoweredArmor: The protagonist of "Final Ninja" wears some, though it's not quite as powerful as most fictional examples, being more focused on [[VisibleInvisibility stealth]].
* PrecisionFStrike: Nitrome is notable for their games generally not having any profanity, though the opening and ending of "Nitrome Must Die" had Austin and Justin's chat screens peppered with SymbolSwearing, and the word "damn" is used early on in "Super Stock Take".
* PrisonEpisode: [[spoiler: "Flipside".]]
* PuppeteerParasite: The protagonist of "Parasite", of course.
* ThePowerOfLove: Twisted in "Parasite." Certain areas are covered in "happy gas," somehow related to an overwhelming force of positive feeling. The title character is unharmed for gameplay purposes, though he strongly dislikes the feeling. His mind-controlled minions [[LudicrousGibs explode]].
* RailShooter: "Graveyard Shift".
* RealityWarper: The protagonist of "Fault Line" can fold the 2D levels in on themselves, causing everything in the folded area to temporarily vanish from existence--for instance, he can bypass walls by folding the space around the walls and leaving empty air behind.
* RunningGag: Ever since "Cheese Dreams", every time the creators have shown a moon, it's been made of cheese.
* RecycledInSPACE: "Office Trap" is basically "Knight Trap" set... [[ExactlyWhatItSaysOnTheTin in the office]].
* RedEyesTakeWarning: The protagonist of "Tiny Castle".
* ResignationsNotAccepted: "Final Ninja". The best solution, of course, is to kill your employer.
* RestrainingBolt: Your MissionControl in "Toxic 2" is an A.I. you've hacked and forced to aid you. It eventually decides it likes you and becomes your SarcasticDevotee.
* {{Retraux}}: '''''EVERYTHING.'''''
** Turned UpToEleven with "Super Treadmill". The game ''[[InterfaceScrew slows down and fuzzes up]]'' [[InterfaceScrew when too many objects are on the screen, and occasionally even "disconnects from the video port"!]]
* RewardingVandalism: "Rubble Trouble" is ''based'' around this -- you're a demolition engineer.
** Although, you lose money if you hit any other buildings besides the one you're trying to demolish, so this is pretty much an aversion.
** Played straight in "Worm Food". You get extra points for eating buildings, although you get most of your food from eating people.
* RiseToTheChallenge: Several levels in "Knuckleheads".
* RobotWar: "Toxic".
* RPGElements: "Blast RPG", naturally.
* SamusIsAGirl: [[spoiler:The protagonist of "Frost Bite".]]
* SandWorm: "Worm Food."
* SaveThePrincess: "Tiny Castle". [[spoiler:[[AvertedTrope Actually, you're just trying to serve her an eviction notice]].]]
** In "Hot Air 2", you have to rescue your girlfriend.
** In "Dirk Valentine", you have to rescue Queen Victoria.
* ScarfOfAsskicking: The hero's scarf in ''SkySerpents''.
* ScavengerWorld: This is the entire point of "Steamlands". It's imperative to steal your enemies' tank parts after your destroy their engine room.
* ScreenTap: In "Test Subject Blue", the scientist occasionally taps on the window in the test chamber.
** In "Test Subject Complete," one of Dr. Nastidious's soldiers takes it a bit farther and pounds the glass with his fist.
* SecretLevel: Several in "Toxic 2", accessed through blue teleporters in out-of-the-way areas.
* SegmentedSerpent: One of the nastier enemies in "Graveyard Shift", and the final boss in "Aquanauts". Naturally, you kill them bit by bit.
** The ones in "Bullethead" can take relatively few shots, but are only hurt when shot in the tail. They move left-to-right and right-to-left, descending a little with each pass, and are long enough that you only have a small opening to shoot the tail before another part moves in front of it.
** SkySerpents is based entirely on killing these.
* SelfDeprecation: "Nitrome Must Die". It's even in the title!
* ShootTheShaggyDog: Subverted in [[spoiler: "Enemy 585" when it looks like the titular character will walk off the cliff to their doom (and the player is unable to help) but stops and turns around]].
** Played straight in [[spoiler: "Cheese Dreams", which ends with both you and the ship you just escaped from getting [[AlwaysABiggerFish eaten by a larger ship.]]]]
** "Ditto" ends with [[spoiler: the protagonist finally finding the exit to the cave they are trapped in, only for their reflection to go through it first. This not only traps the poor creature, but turns them into a reflection themselves. They then act as the reflection for the next person to get trapped, presumably starting the cycle all over again.]]
* ShoutOut: Many in pixel form in "Skywire VIP". In fact, that's practically the whole point.
** A tutorial box in a remote place in "Final Ninja" says, "The ninja must be like a snake, sneaking through the darkness, hiding from the light. To never be detected is the way of the [[Franchise/MetalGear solid snake]].".
** In "Chisel 2", a level set in an asteroid belt has the [[{{Asteroids}} asteroids as green outlines]]. The VoiceWithAnInternetConnection comments that it hasn't been used since 1979.
** As explained below, the Uncle from Super Treadmill is named [[Film/NapoleonDynamite Uncle Rico]].
** ''Enemy 585'' has many to ''SuperMarioBros'', consider the layout of the "boss" room at the start.
*** "Mega Mash" has it's first level pretty much identical to the first level of Super Mario Bros, apart from the bit where you turn into a spaceship.
* {{Soliloquy}}: Uncle Rico does one in Day 24 of "Super Treadmill", summing up his true motive:
--> '''Rico:''' That stupid boy is going to make me lose the bet! I can't afford to lose, the price is too high! I'll make that boy super thin, even if I have to get on that treadmill myself! [[EvilLaugh HAHAHAHAHA!]]
* SpikesOfDoom
* TheSpiny: "Frost Bite" has a few.
* StealthRun: Another thing that gets you bonus points in "Final Ninja".
* SteamPunk: "Dirk Valentine and the Fortress of Steam", not surprisingly.
** There's also "Steamlands".
* StrippedToTheBone: The death animation in "Toxic" is surprisingly gruesome.
* SugarApocalypse: The technology-free garden world on which "Parasite" is set is full of cartoonishly happy animals and benevolent nature spirits. The titular parasite kills the animals, harvests the spirits, and turns the entire world into a barren waste.
* SuperDeformed: The signature visual style in the more recent games.
* SuperDrowningSkills: Explained as part of TheReveal in "Twang" -- [[spoiler:you [[TheBet bet a substantial amount of money]] that you could get from one side of the ocean to the other without using a vehicle and without getting wet.]] Also present, with a handwave, in "Parasite".
** Icebreaker requires you to get the Vikings in the boat lest they drown.
* SurpriseCreepy: "Canary" puts a cute little birdman in a SurvivalHorror situation. "[[TheVirus Join us]] . . ."
* SwordAndSandal: "Double Edged".
* TakeThatMe: In the background of one level of ''Nitrome Must Die'', there's a whiteboard labeled 'New game ideas'. One idea that's circled and underlined is "Cheap Sequels".
* TagLine: "changeType()" has "Rewire The Platformer!".
* TeleportersAndTransporters: The one and only ability of the main character in "Mirror Image"--he can't even walk.
* ThemeNaming: The leads of "Nitrome Must Die" are named A'''ustin''' Carter and J'''ustin''' Bennet.
* TomatoSurprise: The end of "Tiny Castle", where your knight, bound to save the beautiful princess, turns out to be [[spoiler: a debt collector chasing down the princess, who refuses to pay rent on the castle.]]
* TrialAndErrorGameplay: "Cave Chaos" manages to be {{Masocore}} ''without'' being NintendoHard, on the basis that you have to memorize how to avoid several deaths per level.
* UnexpectedGameplayChange: We have "Test Subject Blue", which plays out like VideoGame/MegaMan meeting VideoGame/{{Portal}}, then "Test Subject Green", where it's still the same formula, but not long after that we get "Test Subject Arena", where instead of getting a food pill, the blue and green enzyme fight with proton/enzyme blasts.
** There's a similar example in the "Skywire" series. The first sequel, "Skywire 2", is simply a bunch of additional levels to the original. "Skywire VIP", however, has you guessing who all the people you've been riding around are supposed to be.
** There's also "Mega Mash", which is a gameplay roulette of seven different sub-games with an overall puzzle element. The premise is that you're playing a broken Nitrome Enjoyment System cartridge which is constantly glitching out.
* UpToEleven: Nitrome takes their small retraux games to new heights with ''Gunbrick''. The entire game is played in the tiny 50p x 50p icon! They have a full screen option so you don't scream in pain from the eyestrain, thankfully.
* VerbalTic: Ribbit, Ribbit in "Ribbit" constantly says "ribbit", ribbit.
* VillainProtagonist: "Parasite" is about as clear-cut as you can get -- you destroy entire planets both for survival and because it's fun. "Worm Food" is another staring example. A few other games, like "Castle Corp", have protagonists who're {{Anti Hero}}es.
** [[spoiler: "Droplets"]] has a bizarre twist example. [[spoiler:The bunnies you've been carefully stop from dying are an evil invading army.]]
** Austin Carter and Justin Bennet from "Nitrome Must Die".
* ViralMarketing: [[http://www.nitromemustdie.com/ Nitrome Must Die]].
* TheVirus: ''Canary'' and ''Cave Chaos 2'' approach this in different ways.
** In ''Canary'', [[spoiler:the protagonist is never infected, but [[MissionControlIsOffItsMeds his mission control is, urging him to "join us."]]]]
** In ''Cave Chaos 2'', worm-like enemies crawl into the protagonist's ear to reshape him into something halfway between his normal self and the standard enemies in the first game. (It's [[BodyHorror even more disgusting than it sounds]].) This forces him to constantly move forward, just like those enemies, although he can still turn around. It also changes the level-complete animation--instead of dancing around happily, he'll stand in one place for a moment, then suddenly start vomiting (apparently purging the worm, since he's back to normal in the next level.)
* WaddlingHead: The vikings in the "Ice Breaker" series are a non-enemy example.
* WallCrawl: The protagonist of "Glassworks", due to the special gloves he wears.
* WeirdSun: The sun in "Ribbit" has bulging eyes, a slightly downturned mouth, and clenched teeth, and appears to be in significant pain. This is never explained.
* WhatHaveIBecome: Ribbit's reaction to becoming a {{Mix and Match Critter|s}}, though it skips the {{Wangst}} stage and proceeds straight to {{Revenge}}.
* WombLevel: The entire game in "Nanobots".
* YouBastard: The end of "Parasite", although it's PlayedForLaughs.
* YouHaveResearchedBreathing: In ''Nitrome Must Die'', the Bullethead weapon is identical in almost every way to the regular pistol... except that it shoots ''up.''
