I've just done about the first four levels. I'm really liking this game. It's essential to go and flip the controls in the settings so that tapping left rotates you to the left and vice versa, but once you've done that it's good. The controls still take a lot of getting used to, but that's kind of the point of the game. Wonky physics though, where gravity only has an effect on you when you aren't touching the screen.
