The game is pretty challenging and the idea is pretty original too. The only issue that I have is that I feel that there’s no way to “master” these controls. I feel (maybe it’s just me) that the jumps I make are a little too random. Most of the time, I can’t find a relation between the shape I’ve formed, and the height it reaches when jumping.
But that’s just me, of course, and it doesn’t mean that the game was boring or anything, just a little frustrating at most.
Good job!
