* AlternativeCharacterInterpretation: Is Lilac an AllLovingHero who will to do anything to protect her friends, or is she an impulsive daredevil who puts innocent people in danger and will risk the safety of the universe on a dime to save a child she's known for all of three days?
* AnnoyingVideoGameHelper: During the end bosses of Fortune Night and Jade Creek, the other playable characters will show up to provide health and get some hits in. [[DownplayedTrope They're not exactly annoying]], but they take away a bit of the challenge of these fights and are technically not even needed to defeat these bosses, making for fake teamwork.
* AnticlimaxBoss:
** The final battle with Serpentine is an absolute joke as Carol, as you just have to hang onto the wall and you can dodge every one of his attacks. From there it's just timing your attacks so you can run back to the wall before he punches you.
** As Carol, Spade is a hilariously easy pushover after fighting [[CrowningMomentOfAwesome ninety-nine ninja on motorcycles]] to get to him. All it takes is a few correctly-timed jumps on the panels to avoid his attacks and you're free to slash away at the panda.
** Milla can utterly dominate Brevon's second form. Since his attacks mostly consist of blasting, her shield can deflect all of them back at him, and can be further damaged with a Super Shield Burst. Fly away from his dashes, and she can take him out in under two minutes without a scratch.
* BestBossEver: Special mention goes to Brevon's third and final phase with Lilac and Carol. No cheap tricks, no summoning minions, just AwesomeMusic and a nice, clean speed vs. skill fight.
* BreatherLevel: Final Dreadnaught 2 is long and maze-like with plenty of DemonicSpiders, a deoxygenated section, and [[ThatOneBoss a tough boss]]. Final Dreadnaught 3 is shorter with plenty of opportunities to speed through the level and [[BreatherBoss a much less difficult boss]].
* CompleteMonster: [[BigBad Lord Arktivus Brevon]], an alien GalacticConqueror, conquered hundreds of worlds, killed and corrupted thousands of heroes. During the events of Freedom Planet he is trying to steal a power artifact known as the Kingdon Stone, which the primary source of power of Avalice. He [[EstablishingCharacterMoment opens the game]] by [[OffWithHisHead beheading the King of Shuigang]] in front of his son, and then brainwashing that son into his own loyal puppet. He then uses his influence over Shuigang to increase tensions between the Three Kingdoms of Avalice and provoke an energy crisis in Shang Mu, eventually leading to him obtaining the Kingdom Stone. [[spoiler: After Brevon captures [[TheHero Lilac]] when she attempted to rescue Torque and the Kingdom Stone, he proceeds to [[ColdBloodedTorture mercilessly torture her]], through a combination of wounds (including cutting off her PrehensileHair), ElectricTorture, and [[BreakThemByTalking Breaking Speeches]]; the electric torture and effects of the wounds are seen on-screen.]] His worst actions come when the main characters invade his battleship as it prepares to fly into space. Brevon's initial tactics include opening the airlocks, [[BadBoss forcing his own loyal general]] Serpentine into a [[TransformationTrauma painful transformation]] to better fight you, and turning off the atmosphere in his ship. One of his most despicable acts involves [[spoiler: using the [[WouldHurtAChild naive and innocent Milla]] [[BreakTheCutie as a hostage at knife-point]] to prevent the main characters from recovering the Kingdom Stone, then forcing the previously mentioned transformation to [[BrainwashedAndCrazy turn Milla into a monster and forcing the characters to fight their friend]].]] When confronted by said characters with [[ThisIsUnforgivable refusal to forgive him for what he has done afterwards]], he simply shrugs and says that he has no use for forgiveness from someone "[[FreudianExcuse putting his homeworld at risk]]" for the very stone that he describes as an oversized battery. [[spoiler:In Milla's story, Brevon ambushes Carol out of nowhere, attempts to throw Milla into despair with breaking words concerning what happened between him and Lilac, and, after she severely damages his mech armor, makes one last attempt on her life by attempting to choke her to death in a murderous fit of rage.]] Cruel, heartless, sadistic, and motivated by nothing more than a desire to continue his dreams of galactic conquest, Brevon [[KnightOfCerebus really stands out]] in an [[VileVillainSaccharineShow otherwise-lighthearted]] game.
* CrazyAwesome: Carol is a wildcat thief that rides a motorcycle that can drive up walls, loops, through enemies, and up ladders while performing flips and kicks, and casually mentions being trained as a ninja.
* DemonicSpiders
** DNA Cannons, so named due to the double helix shape of their lasers. They don't appear in too many levels, but when they do, ''beware''! They can shave off a huge chunk of health with a single blast and are always placed in the most inconvenient of places. Crosses over into HellIsThatNoise due to the distinct sound the cannons make when they fire.
** Shade Troopers, first seen against the boss of Jade Creek and continuing to appear from then on. They take quite a bit of punishment to kill, move around erratically, seem to open fire at moments you are most vulnerable, and will chase you throughout the level if you attempt to flee from them. Worse, they tend to appear in groups.
* DisappointingLastLevel: The first part of Final Dreadnought, Round 4. The final level starts with a vertical series of disappearing platforms, coupled with teleporters that send you all the way back to the bottom if you touch them. This results in some very frustrating TrialAndErrorGameplay that can easily take ten minutes if you don't get the platform timing exactly right. The problem is even worse when playing as Lilac. Carol can skip most of this segment by simply jumping up the walls, whereas Lilac's air dash is much harder to properly control.
** What doesn't help is that the game pulls a huge PlayerPunch right before this by [[spoiler:having Brevon turn Milla into a BrainwashedAndCrazy monster that Lilac/Carol is (seemingly) forced to kill in order to stop]]. Lilac/Carol is [[RoaringRampageOfRevenge furious]] and naturally wants to rip Brevon to shreds... and then it cuts to a level where you have to take your time and make very precise jumps.
** Fortunately most of the issues with the level were addressed with patches. Annoying enemies disappeared, and the first vertical section was streamlined to avoid unnecessary frustration. Now, the stage is designed to be one [[BreatherLevel last breather]] placed between intense Final Dreadnought 3 and the FinalBoss.
* EarWorm: Dragon Valley 1, Relic Maze 2, both Fortune Nights, and Thermal Base 2's themes are particularly hummable.
* EnsembleDarkhorse:
** The bird guard, who appears in the background of a few cutscenes (and pilots the hovercraft in Jade Creek) and who's only line is a disgruntled "quack," has proven to be surprisingly popular. He even got a joke profile on the website for the sequel.
** Neera Li, the boss of the first act of Jade Creek. Despite being a bit of a jerk and half the reason why our protagonists end up in prison, she gets a lot of fanart, some players even thought she would be a bonus character with her detailed animations, only to be disappointed.
** Mayor Zao as well. With his LargeHam tendencies and the RunningGag of gaining a +5 in whatever he's doing, he delivers many funny moments.
* FanficFuel:
** Torque's previous missions chasing Brevon, all strongly implied to have ended in disaster on numerous other worlds.
** The Coalition of Planets, where hundreds of worlds with intelligent life reside. And as hinted, might Avalice soon join now they've officially had First Contact?
** Carol and Lilac's time in the Red Scarves and their relation to Spade. Not to mention whatever led him to cross a line they refused to, and their defection.
* FriendlyFandoms: With ''VideoGame/ShovelKnight'' fans, as its 8 bit older brother. Both are indie-developed {{Retraux}} games funded on ''Website/KickStarter'' that came out within a month of each other, are throwbacks to the golden age of platformers, and have detailed pixel art and excellent gameplay.
* GameBreaker: Though [[DifficultButAwesome not necessarily easy to play]], Milla is well worth the patience as she can fly, has no special meter to get in the way of spamming Super Shield Bursts that do an incredible amount of damage, can use the recoil from said Bursts to do a FlashStep that accelerates to Lilac's, and can deflect many attacks that can make short work of the bosses. This is counterbalanced with a health bar that's only half the size of Lilac and Carol's, but if you're fast enough this is rarely a concern.
* GoodBadBugs:
** In the first demo of the game, Lilac could fly if she restarted the level while under water.
** In Relic Maze, it's quite easy with a bit of timing to jump off the handles that open staircases to land before it closes, letting you pass through walls. The handle at the top section in particular can be used to slide through the wall connecting the upper and lower portions of the temple since they occupy the same area on the map. Boosting through the correct wall will warp you to the miniboss, skipping the second half of the area entirely.
* LesYay: Carol and Lilac, perhaps inevitably. They live in the same house together, have a TomboyAndGirlyGirl dynamic, never seem to leave each other's side on missions, and are very close friends. The separation scene can easily be taken as a temporary breakup, Lilac is too [[ItsNotYouItsMyEnemies worried for Carol and Milla's safety to put them at risk]]. And with Milla for all intents and purposes adopted as a child to take care of, she HasTwoMommies.
* {{Moe}}: The girls are pretty cute and endearing. [[TheCutie Milla]] is the obvious candidate with her inquisitive puppy behavior. [[GenkiGirl Lilac]] with her peppy determination and [[TeamMom maternal affection]]. And [[CuteKitten Carol]] who's sly behavior as a wildcat and the tomboy of the group qualifies too, even if she'd not admit it. [[{{Adorkable}} Torque]], for the female players.
* MoralEventHorizon: If Lord Brevon didn't cross this before the game started, he ''definitely'' did after [[spoiler:torturing Lilac via electrocution machine in the end of the Thermal Base Stage]]. And by the time he [[spoiler:turns the sweet and innocent Milla into a creepy mutant monster]], he hasn't crossed the line so much as he has catapulted himself over it. To be specific:
** [[spoiler:He uses Lilac as a means to force answers out of a captured Torque, threatening to activate the machine on her if he doesn't cooperate. Only a few seconds after the machine is turned on and Lilac is left screaming in agony, Torque is forced to reveal that he is the last of his crew. Despite this, Brevon [[KickTheDog activates the machine ''again'']] on Lilac. He soon reveals that he was more interested in testing Torque's resolve than any answers he got from him.]]
** [[spoiler:By the time the others rescue Lilac, a good portion of her skin is ''burnt and charred'', Lilac's screams during the torture do nothing to help this.]]
** Even more horrifying about this is the fact that [[spoiler:her long twin strands of hair that she uses to attack have been cut off before the torture even begins and are draped over a rail. The ends of the strands are red, suggesting that it isn't hair at all, ''but a part of her body'', meaning that Lilac has already been mutilated beforehand]].
** [[spoiler:Lord Brevon turning Milla into a creepy [[AmbiguousRobots techno-organic monster]]. Doubles as both a PlayerPunch ''and'' a TearJerker. ''Especially'' if you are playing as Lilac, the scream she lets go after the battle is ''heartbreaking'']].
** Before that [[spoiler:is the final fight with Serpentine, who has also mutated into a horrible monster. Whatever Brevon did to Milla, [[BadBoss he must have also done to Serpentine, his own right hand man!]]]]
* {{Narm}}: The player exploding in a cloud of feathers/tufts of fur when they're crushed or killed by certain attacks.
** "''What'' do you want with '''''US'''''?!"
** "Examine the fragment! ''EXAMINE IT''!"
* NarmCharm:
** The game's voice acting is evocative of English dubs for the UsefulNotes/PlayStation or UsefulNotes/SegaSaturn. With the retraux presentation and the actors' sincerity, it fits the rest of the game's aesthetic of a localized [[UsefulNotes/TheFifthGenerationOfConsoleVideoGames Fifth Generation title]].
** Carol's physics defying motorcycle is both hilarious and awesome to watch in action.
* NeverLiveItDown:
** While it's true that the game started out as a Sonic fangame, it has clearly evolved and grown over time with many other homages to 16 bit platformers. This won't stop detractors from saying it's a Sonic ripoff and accuse Lilac of being a bad fan character.
** The cutscenes: Many critics regard the Adventure Mode with bile, as they accuse the scenes of being pointless filler that break the flow of the game, or overly long, targeting the sleepover and dinner sections as examples. Though it could be said that the cutscenes can be longer than strictly necessary, some reviewers go on about them like it's a ''VideoGame/MetalGearSolid'' installment.
* {{Padding}}:
** Shortly after discovering Milla and Torque, the girls have a sleep-over at Lilac's treehouse. It has nothing to do with the story and seems to exist solely to lengthen a break in gameplay that's already been going for 5 minutes.
** Another moment similar to this happens later when the heroes are invited to and attend a royal dinner party. The kicker? This happens almost immediately after [[spoiler: the Kingdom Stone gets stolen. Mayor Zao justifies it by admitting that it would take time to repair his airships, which were damaged in the attack]]. It mainly serves as exposition in their conversation to explain to Torque and the audience the legend of the ancient dragons.
* PlayTheGameSkipTheStory: Classic Mode, for players that don't like the voice acting or simply don't care for the plot. It removes all cutscenes and most dialogue, merely advancing stages.
* PlayerPunch: Brevon pulls a few of these. For examples, [[spoiler:he has Lilac horribly tortured and turns Milla into a monster]].
* SurprisinglySimilarCharacters: Lilac has a lot in common with [[VideoGame/{{Shantae}} Shantae]] of the titular game. Let's see: they're both {{Action Girl}}s whose main form of attack is their [[PurpleisPowerful pur]][[SupernaturalIsPurple ple]] PrehensileHair, they're both descendants of a race that's no longer around and they're both friends with playful, green girls who are a bit more morally grey than they are. (Carol's fed up with Lilac's ChronicHeroSyndrome, while Rottytops worked with Risky to get Shantae's brain once.) Take into account the fact that they're both trying to stop the villain from getting a precious artifact to use for nefarious purposes and this might start to bleed into SurprisinglySimilarStories as well.
* SuspiciouslySimilarSong: [[https://www.youtube.com/watch?v=6ET4sMyr_M4 To The Rescue!]] sounds a lot like [[https://www.youtube.com/watch?v=ZocM0ZCnH5Q Proof of Courage]] from ''VideoGame/MegaManBattleNetwork'', even sharing the role of a uplifting hero theme.
* ThatOneAttack: Brevon's Knife Slash. The game makes sure to show you how dangerous that thing is and when you finally battle Brevon if you let that attack land on you '''it will hurt like hell'''.
* ThatOneBoss
** Spade. He's not too hard if you're Lilac, and is fairly easy if you're Milla. If you're playing as Carol, however, he's one of the hardest bosses in the game, as she lacks the speed of Lilac to keep up with his FlashStep dashes, and she doesn't have a shield to reflect his projectiles like Milla does. What really hurts is the fact that his attack pattern seems designed to punish aggressive strategies, meaning you're only going to die that much faster if you try to chase after him.
** Prince Dail's Thunderbird is particularly difficult as Lilac. His gimmick of using wind to blow you off the stage, coupled with his homing attacks, lasers that can cover all but a small percentage of the screen, the fact that you have to attack a dozen feathers as separate hit boxes to damage him, and his rush attacks that can down your health bar in four hits. What [[{{Pun}} pushes it over the edge]] for Lilac is her floaty jumps and Cyclones that previously used wind to her advantage can knock you to your death if you're not precise with your jumps. And that goes double for her Dragon Boost, which will get you killed two times out of three if not timed and used sparingly. Carol can at least use her special to cover a wide range to down his defenses and pass through attacks with her invincibility frames.
*** His Shadebeast in Battle Glacier is even worse. He spends most of the fight high above the ground where he's hard to reach. This isn't much of a problem for Carol as she can scale the walls, but Lilac needs to Dragon Boost up there, and the Dragon Boost requires a full gauge. And all this time, he's spamming BulletHell attacks. The only time he comes down to ground level is when he's preparing his most devastating attack. At least the [[FlunkyBoss mooks]] give you health.
** On the flip side, there's Mega Serpentine as Carol. On a flat plane with one wall on the far right end, a boss that loves to spam BulletHell attacks, and gets his own temporary invincible shield, it's as if he were designed to be as counterproductive with her melee attacks as possible. And since he loves to run off once hit, there's no hope of spamming a sustained special attack, unlike with Lilac who can quickly catch up to him.
** Brevon's second phase is probably one of the most difficult boss battles in the game, particularly with Lilac and Carol. His mech moves fairly quickly, its attacks are extremely unpredictable, and its arm cannon follows you as it shoots at you, plus it has an attack where it gathers lots of energy and releases it across much of the area.
** Even by FinalBoss standards, Brevon's final form is nigh-unanimously considered ridiculous. So much so that he was one of the bosses that was toned down in difficulty in a later patch because the creators found the huge number of deaths to him unacceptable. And he's ''still'' easily one of the hardest bosses in the game, as a final boss should be!
*** It's also worth noting that Brevon is the ''only'' boss in the entire game to have a life bar, as if the game is saying "You know all those other {{Badass}} people and giant robots and monsters you fought? Yeah, those guys were chumps. ''This'' dude is the real boss. Have fun getting your ass kicked!".
*** Even mere impromptu health bars seem to be the domain of the hardest lategame bosses: Brevon's first two forms have health bars ''as a stage piece'', whereas Prince Dail at the Battle Glacier (as mentioned below) also has one in the form of a pile of mooks. The closest clue the player gets with any other boss is that it ShowsDamage, and sometimes not even then.
* ThatOneLevel: Battle Glacier. For starters, it's the longest level in the game and starts with an UnexpectedShmupLevel. It's also home to just about every {{Goddamned Bat|s}} and {{Demonic Spider|s}} you've seen in the game thus far. Worse, they tend to come in large groups and attack from multiple directions, making it very difficult to get through some sections without taking a lot of damage. To top it all off, Prince Dail is the boss and is quite a jump in difficulty compared to most of the bosses encountered so far, going so far as to incorporate BulletHell into his attacks and spawning a large number of [[FlunkyBoss annoying lesser enemies]] in the process.
* TheyCopiedItSoItSucks: Given the game's numerous similarities to ''Franchise/SonicTheHedgehog'', this complaint was inevitable. It was especially common before ArtEvolution changed Lilac's species from a [[CaptainErsatz hedgehog]] to a [[InstantAwesomeJustAddDragons dragon]]. More prominent gameplay similarities to the series, such as rolling, were also gradually phased out if deemed unnecessary.
