I bought it , played like 4 stages. The controls definetly take some getting used to, and you really have to pay attention to where you are going in the stages, if you passed a sign a minute ago saying 50 cm only and you have a 48 cm ball, go back there when you get that last 2 cm. Also, judging carefully where to go grab stuff and when is of key importance, some spots in the game can only be accessed at the smaller sizes properly so make sure to go to these places, like the lego bridge in the house level , once you get above 10 cm you'll just sticky the bridge.
