Find and kill the chickens. The game's quite cool, but it's got some problems: you have to kill one chicken more each level. You also get more time to kill 'em and that's a bad thing, because once you know the level a bit, you'll always have enough time. You can't loose. Furthermore, after level 9 you restart in level 1 again. The only thing remaining is to get the highest scores possible for each level. This isn't really exciting, since it depends on luck mostly. Also time left ain't displayed correctly.
