You control a little ballista tower. Your goal is to shoot the zeppelins out of the sky and protect the wagons from being destroyed by the zeppelins cannons. When there are no more wagons to shoot, the balloons will turn on you! You have three lives. Defeat all the balloons to win the round.
How to play:
Touch and hold the top of the screen to ready up an arrow. The further up the screen you drag from, the further back you can pull the ballista, and the further the shot will fly. When you have pulled the arrow all the way down you can aim. Lift your finger to release the shot.
Shoot those balloons!
