Dear franny22,
I played like 5 levels the game was good but I caught some little things that you should fix. First of all when level changes music restarts and that is bad, you should change it. Secondly these green clouds disappers when my head hit to there I suggest just walking on it makes these clouds disappear. Nevertheless the game was good but you should fix these small things continue making games.
Cheers!
