Fun to play, but physics are really, really wonky. Even though that benefits the player (objects seem to be coated with "adhesive" which allows them to stick on slopey angles on each other) it also breaks the premise - this is aggravated by the really fast count-to-3 which allows progression even if a block/platform is doomed to fall on the side.
Well, at least the game isn't ridiculously hard to play that way.
