Nice game. It needs more polish though, for example it's weird how the jump input doesn't resolve if you touch it mid-air, even though in my mind I already finished the level. Having a deterministic space, like by using a grid, can help a lot in these situations. Also, enemies appearing out of thin air is very cheesy, and feels unfair, and those platforms at the level head really communicate that I should be able to move through them. These are small things, but they're tremendously important.
Good luck!
