Simple yet fun, controls seem a bit weird but easy to get used to after a few tries. Air control would be great, but being unable to control your character mid air also adds some kind of unexpected fun in my opinion.

Nice game.

Might be simplify collision for player and give player more control in air to make it more satisfying.

Also, restart the level when you jump out from the level could help with edge cases.

Great work with a simple, easy to understand concept!
