It was an interesting experience. I got through by utilizing the Ponysapien walking method -- QP WO to walk, which typically can force weight easily into the back legs, and OP for book smashing. The controls are difficult, but I'm guessing that is, in a way, the premise. My only real complaint is that the visual gets rather stale after a few minutes.
Also, the ending makes me want to punch my screen in. I'm not going through all that again.
