Almost last game I test for the jam... And I'm jealous!
The conceit is fun. I love only jumping!
Few things, I would suggest:
- some kind of way to see past attempts (like replay meetboy style),
- If I'm not mistaken there is some air control, maybe tutorialize it more
Art and level design is banger! I'm curious, are you using ogmo editor for the level design ?
Maybe the best game of the jam i've played!
