Really fun entry! I think the movement could be a bit tighter, as right now it feels floaty, particularly the jumps. But I'm keeping it tabbed so I can continue with it later. I've got to at least pick up all the gems!!
I'm glad you are having fun with it! It is a bit floaty yeah, although it is slightly intended to make bouncing around more fun and less "realistic". I'll look into making it slightly tighter though as I'm working on the post jam update(s) :D
