The game will only work once after a hard reset on the 3G. After that, attempting to start the game will result in crashes to the home screen or it will start in an unplayable state. By that I mean it will be running very very slowly and the top status bar remains visible.
When the game works on the 3G, it is a wonderfully fun game with great graphics and truly unique gameplay. I cant recommend this game for anyone with a iPhone 3G and its equivalent iPod but anyone with a 3GS or above should give it go.
