Chillingo has launched Sheeple Chase – a racing game for the iPhone and iPod touch. In this game, the players have to make a sheep run against other farmyard animals. It features loads of tracks with obstacles, built in track editor. By this game you can also compare yourself with your friends. Costs 1 dollar.
The only problem I see with this game is that it is super addicted. But that does not mean that it is easy to play. After a couple of levels, it gets so hard that it literally becomes impossible to win. [link]
