This is kind of a barebones platformer. There's no sound nor music, almost no horizontal control when you jump, you slide when you land and you can't climb ladders. Not even sure if you can win the second level. It doesn't even have a title screen and you jump straight into the action without any context.
The backgrounds look really good and the character sprites are alright. I believe the latter are procedurally generated? If so, that's a cool use for procgen in a jam context.
