Klein
Klein is a puzzle platformer where the world loops on itself, but with a twist—or rather, two twists. Whenever anything exits the screen, it will return on the opposite side of the screen, but flipped. This is a lot like if the game took place on a Mobiüs strip, except it works both horizontally and vertically.
Controls

very confused on level 6... does the little square box thing do something I don't know about? I can't stand on it...
never mind :) I guess gravity is additive

If this is called "Klein" because of Klein bottles, I'll have to say that this isn't a Klein bottle. On a Klein bottle, only one of the sides would flip you.
This game takes place on a projective plane (ℝP²). Notably, the fundamental group only has two elements whereas the fundamental group of a Klein bottle is infinite.
Yep! This is something I contemplated and researched when ideating the game, and decided that "Klein" was a catchy enough name to be worth the misnomer. Glad to see someone else who's enough of a nerd to notice :)
