**Description** Asses everywhere! Donkeys are secretly plotting against us. They’re up to no good. Do you think you have what it takes to save the world from catasstrophe? Most people can’t even tap one; can you smack it all? **SAQ (Sometimes Asked Questions)** How do I play? Wait for the donkey to shoot out of the cannon. Tap anywhere on the screen to hit it with a bat. Score as much points as possible. What is the point of the game? Save the world from disasster. How do I score? You need both luck and skill, or an overwhelming amount of either one. I have amazing hand-eye coordination, but I can’t even score one. What in the world! You are either really unlucky or lucky depending on how you look at it. I have a 7-leaf clover for luck and I can't even score one! Why! Maybe all your coordination skills went into your feet-eye coordination rather than your hand-eye coordination. I would suggest trying to use your feet. **Conclusion** If you have read this far, then hurry up and go download the game, and smack some ass!
