Hey there, I tried out your game! I actually liked the movement, I think the jumping would sometimes bug out and it wasn't always clear when I could jump more than once. I got Rick Rolled which was cool. As some of the other commenters have said it'd be interesting to choose your power directly instead of hitting your head multiple times to do it. I'm still choosing directly, it just takes longer.
Good project, check out my game if you have time!
