Sort of like Pixeljunk Eden. Don't let the flowery decor, trippy music, and effortless videos of floating through space deceive you: it masks a brutally hard platformer which if my friends were not so committed to each other would probably have caused a divorce after failing to properly catch somebody at the top of the last level, which causes BOTH players to fall all the way to the bottom. And its a long way down, with plenty of time for bitter recriminations.
