Focus on the red tank. It fires by tapping the screen (anywhere). The bullet will fly with the last angle of the tank. When the bullet hits the other tank, the old one will be destroyed and it will become the active tank.
Tank Spin is a shooting game with levels. Your goal is to keep only one tank. After you miss your target, the game is over. There are two types of tanks included. The active (red) and the passive (blue). The red is the tank that will execute the shot.
