That was a fun little puzzle-platformer. Especially liked the invisible platform right at the end of the 2nd level. Wish there was more to play; good job.

nice little game! It's a little weird you didn't just disallow jumping if you went over. the up arrow doesn't restart the level, so you can just use that to jump and you can beat a level with negative jumps. the boss is really neat though, definitely my favorite part

I was about to give you a low score on theme, and it dawned on me what you've done here. I let out an audible groan.

Mechanically the game seems sound. I do feel like level design is a bit hostile in places, but the game plays fast enough that a bit of experimentation was fine.

I think you're probably aware of the graphics and lack of polish, so I'll leave that feedback to your imagination. But I do think there's some interesting gameplay potential here. It's worth playing around with a post compo version if you get some time. I think it could be a lot of fun as a puzzle platformer.
