Quite a basic idea but nonetheless done well. It's quite addictive and there are no extra frustrations that counter the game's adictivness. The soundtrack is briliant too - nice choices. The game really plays as expected and matches my expectations quite well. The tricks are well done and make for a very interesting game.
Overall if I had to say I had a problem it would be with the hit detection. The shapes seem to have outstreched their boundaries in this game.
