* SugarWiki/AwesomeMusic: ''Non-Human'' has ''[[https://www.youtube.com/watch?v=i6F0OY74P3Y multiple]]'' [[https://www.youtube.com/watch?v=4YIMg2nMFPs awesome]] [[https://www.youtube.com/watch?v=QywzeWK3cv8 stage]] [[https://www.youtube.com/watch?v=Ii53XfJPSEM musics]] as well as [[https://www.youtube.com/watch?v=vGxyFY4gUSE boss]] [[https://www.youtube.com/watch?v=MWae505qtLo musics]]. The original music only appears at the end section of the game. The first stage of ''STREEMERZ'' also qualifies.
** The soundtracks from [[https://www.youtube.com/watch?v=M_zwR6Fzz8U Sombreros]], [[https://www.youtube.com/watch?v=xrPkXIPs3Vc Illuminator]], [[https://www.youtube.com/watch?v=LFpXldUFweA Bubblegirl Rozy]] and Meong certainly qualify as well. "Sombreros" in particular converts a bland, repetitive song into a more memorable one with upgrades to make it sound more like the theme of a Spaghetti Western.
* DemonicSpiders: The disembodied mouths in ''Non-Human''. Their tongue lash hurts a lot and has longer range than the mechs' regular attacks unless you get enough range powerups. Normally you can jump it, but you'll usually have to retreat as they tend to appear in enclosed spaces. They also have quite a bit of health, which means that you'll need to advance/retreat a few times to kill them.
* GameBreaker: The Bug-Torcher 5000 in City of Doom. Deals huge damage (1-2 bursts will kill a [[GoddamnedBats window bug]]) over a large, medium-range area as well as destroying enemy projectiles. Handy for the shot-spamming first boss. It guzzles ammo, but this can be solved by tapping the attack in bursts.
* GoddamnedBats: The flying disembodied hands in ''Non-Human''. These things fly upwards out of [[DenialOfDiagonalAttack regular weapon reach]], then do a diagonal rush towards the player. They hurt a lot and can take quite a bit of damage for a small hand, and worst of all, they attack in groups!
** ''City of Doom'' has the "window bugs". They take a good bit of hits to die, hide in windows, and only become vulnerable when they pop out and fire three aimed shots. Thankfully the Bug-Torcher 5000 incinerates them with great ease.
* HilariousInHindsight: ''WebVideo/TheAngryVideoGameNerd'' did a review of ''VideoGame/{{Action 52}}'' where he commented on ''Rocket Jockey''. He mentioned on how it would be cool if you could use the lasso instead of the game being just another shoot-em-up. The remake does just that!
* MoralEventHorizon: Dr. Murdon in ''Non-Human'' does this during the introductory cutscene. The heroes are closing in on him, so he pumps mutagen into a nearby village and turns all the innocent villagers into the titular monsters.
* NarmCharm: The intentionally goofy and old-school ([[IntentionalEngrishForFunny read: full of grammatical and spelling errors]]) script in ''STREEMERZ'' can certainly get more than a few laughs.
* NightmareFuel:
** The monsters in Non-Human are either disembodied body parts or mutated zombie-like abominations, which are all ''very'' unsettling. Even worse still is that they [[WasOnceAMan were once human]] until Dr Murdon turned them into the titular horrors.
** [[https://www.youtube.com/watch?v=yag5c_l2C-8&t=3m57s The ending]] to ''Jigsaw''. It would be horribly gruesome enough even if it didn't come totally out of left field.
* ParanoiaFuel: ''Illuminator's'' gameplay is based in this. Killing enemies requires keeping your flashlight off until it charges up to a certain amount, so knowing where the enemies are is difficult. Even with all the lights you can place to help keep track of enemies, there'll still be plenty of times where you turn your flashlight on and fry an enemy who was only inches away from you and you didn't even know it was there.
* {{Squick}}: Gustav from ''Non-Human''. He coughs up his guts as an attack.
* SuspiciouslySimilarSong: The [[https://www.youtube.com/watch?v=QywzeWK3cv8 third area's music]] of Non-Human is pretty much a remix of [[https://www.youtube.com/watch?v=6biGSrgNUxU Girl World]]. Justified since both musics are made by the same composer.
* TakeThatScrappy: In the good ending of Mash Man the Cheetahmen saves Mash Man from being hanged and beats the crap on the UngratefulBastard villagers.
* ThatOneBoss:
** The Rolling Rollblax in ''Silver Sword'', which forces you to constantly be on the move, and drops mushrooms whenever it's hit, exactly where it's hit, which can very quickly clutter the area and make it hard to move if you don't carefully plan where you hit it. And just leaving it alone while you clean up the mushrooms isn't an option, either, because it quickly picks up speed unless you hit it to slow it down.
** The final boss [[spoiler:the irradiated baby princess]] counts as well, being a BulletHell boss with a tiny, tiny hitbox, which is an absolute nightmare when you can only have one projectile on the screen at a time, let alone while planning the distance your SwordBeam travels to exploit it's ever-changing weakness. The third phase is nigh impossible, due to having to maximize your distance on a tiny, moving target that never, ever wants to just move in the path of your SwordBeam.
** The GiantEnemyCrab[=/=]Bug thing in ''Non-Human''. It has two heads as the weak points, the top fires out a bouncy energy ball while the bottom shoots one that hugs the floor, then moves up when you jump over it. Both of these attacks hurt a lot, are tricky to avoid, and the boss can use both at the same time. Then there's the fact that the boss is [[AdvancingBossOfDoom constantly advancing towards you, limiting your space]] (and deals ''incredible'' amounts of CollisionDamage). Your solution is to shoot the heads to damage him and push him back, easier said than done because the crab can use his claws to guard one of them!
* ThatOneLevel: The final level of ''Meong'' is this and then some. [[MarathonLevel About ten times longer than any other level in the game]], it features every single enemy, obstacle and gimmick present in the previous levels, and even some new ones; along with the tighest-timed sections of the game, a maze made out of [[TemporaryPlatform Temporary Platforms]] that's annoyingly easy to screw up and an obligatory puzzle that's as simple as it's [[GuideDangIt simple to miss]]. CheckpointStarvation is in full effect here, and OneHitPointWonder and HitboxDissonance make this level [[SarcasmMode all the better]].
