I got pretty far in the game (I can't remember where, I think it's where tons of tofu come running at you by the burning truck or something...) and it's pretty hard! I ended up quitting when someone told me that you didn't get a reward of any kind when you beat it, like it was just supposed to be a fun and challenging mini-game for beating the main game- so I think it was a reward in itself. But that's just what I had heard- I'm pretty sure a couple people 'round here beat it.

Well if you do end up getting it on the ps3 there is a nice shiny silver trophy for beating it
