After messing up a "How To Make A Platformer" tutorial, my sprite kept glitching and sinking into the floor. But, I decided to make that into the central point of the game, to make it more unique!
I used the tutorial "How To Make A Platformer" by @okthisisgood (mostly) This is an exact copy remix, but it's from my old account, so it's still my work. Please don't report. Yes, all the levels are possible. Some of them just require JUST the right timing.
