Cool idea :)
I mean it is something original to make controls like this.
But it doesn't really work smoothly for me.
But I found the way - I just chose three buttons for the left hand and three buttons for the right hand and press them sequentially in right direction.
Also I like the art. It look simple and childish but at the same time consistent and looks nice. I mean I really would accept the full game like this. Someone who draw it has cool drawing experience I guess. Or at least very good feeling of art direction :D
