At the beginning of the game, there will be a snail that will move around the bottom of the screen. When a sharp sword or a lump of shit hits the snail, the game ends. What you need to do is to use wooden buckets to guard the snail, not to let the sharp sword and defecate hurt the snail. During the game, you can also add other insects to improve the score.
You can also challenge friends all over the world through Game Center!
