This game is really well done. It's fun, the graphics are great and the motion control works well (it even keeps your view leveled as you turn the iPod/iPhone). The two big problems with it are that there are no unlockables and there is no network play. This game just begs to be played multiplayer over the net and given that it's restricted to single player, it could really use things to unlock. Without either of those things the longevity of the game is limited. It does pass the time, though, and it's a great show off game for your iPhone/iPod Touch. Also, lacking network play seems to be a shortcoming in general with the current crop of iPhone games, not just this one. I don't know if that's because it's impossible with the current developer kit, or if nobody has bothered to implement network play yet. Maybe they'll add network play in a future update, but I have my doubts about it. Given the quality of the game I think the $10 price tag is justified, but I really wish it had net play and/or unlockables. Also, iPhone games need to have downloadable demos, but that's a problem with the AppStore and not with this particular game.
