* HarderThanHard: So you've got levels out there that are rated "Hard" and "Very Hard", but then there's the "Lunatic" category for the nigh-impossible, only-the-most-experienced/crazy-players-should-ever-hope-to-win-this levels.

* ''An Underwater Adventure'': Survival horror platforming (no, really). An alternate take on ''VideoGame/WithinADeepForest'' where the ball never existed and has two parts -- once you finish the first run, go through it again for the second half. Also features multiple endings and some very nice puzzles.

A freeware platformer game by Nicklas "Creator/{{Nifflas}}" Nygren, creator of similar freeware platformers such as ''VideoGame/WithinADeepForest'' and the original ''VideoGame/{{Knytt}}''. Though it only comes with one full level and a tutorial, the game has an integrated level editor and new levels are very easy to install. Several additional official levels have been released (see below), and the game has a very active fan-made level community. Tons can be found on [[http://nifflas.ni2.se/forum/ Nifflas' forums]] and on [[http://knyttlevels.com/ knyttlevels.com]].

* ObviousBeta: {{Invoked|Trope}} by Nifflas in his level called [[ExactlyWhatItSaysOnTheTin "This Level is Unfinished"]].

* HitboxDissonance: Averted. Hitboxes are pixel-perfect. That thing with the spikes that extend when you go near it? You can, in theory, go in between its spikes.[[labelnote:*]]In practice, however...not really.[[/labelnote]]

* SuperDrowningSkills: If Juni touches ''any'' liquid, she dies.
** Justified when the water is colored to look like lava or acid.

* LongTitle: Nifflas seems to be fond of giving the music tracks for the bonus endings these...in nonsensical German! How's "Das Fluffmuffelgebrüggenmüskinegedanken" for a mouthful?

** Pretty common among fan-made levels, as not everyone making them has English as their first language...and not everyone checks their spelling anyway. You're/your, to/too, and it's/its mistakes are certain to crop up (and irk the GrammarNazi in you).

* EnemyDetectingRadar: The enemy detector powerup makes Juni glow red when she is near enemies, though for whatever reason it doesn't work on mechanical ones. It also makes her glow green near entrances to hidden passages (or at least if the creator of the level puts detector alerts by the entrances...).

** Juni in the original levels, and since this is her default look, a great deal of fan-made levels.

* MushroomSamba: The level aptly titled ''[[http://www.youtube.com/watch?v=iGvZa3tiYwY Don't Eat the Mushroom]]''. If you do, you go through a series of trippy scenes from [[spoiler:the Burger King to ''VideoGame/{{Tetris}}'' and ''VideoGame/TheLegendOfZelda'', to teleporting crazily all over the screen, to the background being Creator/JimCarrey in the [[Series/SaturdayNightLive "Night at the Roxbury"]] skit, to pleading for help on Nifflas' forums and Juni climbing a giant version of herself.]]

* HeroicMime: Juni, in the original levels and most others. Several fan levels avert this, though.

* MetroidVania: Most levels are like this.

** One word: Xeia.
* [[OnceAnEpisode Once a Level]]: You ''will'' find an obstacle which can only be passed by running, one which can only be passed by double jumping, one which can only be passed with the umbrella...

* ''This Level Is Unfinished'': ExactlyWhatItSaysOnTheTin, hilariously so.

** Also: "It's '''[[StylisticSuck SECRIT]] ENDING! [[VerbalTic YAY!]]"

* OnceAnEpisode: You ''will'' find an obstacle which can only be passed by running, one which can only be passed by double jumping, one which can only be passed with the umbrella...

''Knytt Stories'' has been billed as an "environmental platformer". Though enemies and obstacles exist which can kill your character, a tiny humanoid named Juni (whose backstory tends to change even between the official levels), the ambient/playground levels tend to be the most popular, thanks to the gorgeous music and sprite packs - both the originals and those added by the level community.

An alternate take on ''VideoGame/WithinADeepForest'' where the ball never existed and has two parts - once you finish the first run, go through it again for the second half. Also features multiple endings and some very nice puzzles.

* EldritchAbomination: Heavily implied to be the "It" of Eric Colossal's unsettling level "It Waits".

* MushroomSamba: The level aptly titled [[http://www.youtube.com/watch?v=iGvZa3tiYwY "Don't Eat the Mushroom"]]. If you do, you go through a series of trippy scenes from [[spoiler:the Burger King to VideoGame/{{Tetris}} and VideoGame/TheLegendOfZelda, to teleporting all over the level, to the background being Creator/JimCarrey in the [[Series/SaturdayNightLive Night at the Roxbury]] skit, to pleading for help on Nifflas' forums and Juni climbing a giant version of herself.]]
* MythologyGag: The alternate endings of some of the Nifflas-created levels. One of them puts Juni at the beginning of ''WithinADeepForest''; another makes her reenact the opening cutscene of ''{{Knytt}}''. There's even ''An Underwater Adventure'', which puts you at the entrance of #modarchive, in a reference to Nifflas' first two games, ''#modarchive story'' and ''#modarchive story 2: Operator Status''.
