Nice! The dude twisting around in messed up ways was hilarious :D
I think scoring should be based on height instead of how many times you move because I discovered you can just press a bunch of keys that are nearby to gain score. I think the chalk is a good incentive to discourage this strategy but I often found myself unable to navigate to it because I it was hard to tell which limb was going to move. Sometimes it wouldn't let me do anymore input if I put all my limbs on a single rock, but maybe that shouldn't be allowed too xD
