Overall, I think this is getting quite close to what I'd like to see in the final game. I really miss the pulling of boxes though. For example, in this game you will never be able to get a box from layer1 onto layer2, without pulling. i don't think I like that, but we can of course limit the pulling to one of the two characters or something...
