OK, this is a pretty cool game. You're goal is to hmmm how can I say this... poo on cars as they pass below you. Sounds like fun? You can also poo on other birds, people, and insects. Only 20 cars can pass clean each level - so try not to miss them!
Try to avoid colliding with things as they zoom towards you. Depending upon the size of the object, you will lose health points. To increase health try to eat flying fish.
