When you click the green flag, there will be a cannon and that cannon will follow your mouse-pointer. The cannon is also draggable. When you click anywhere on the screen or press the space-bar, a ball will be fired. You can chose the force of the ball by how close your mouse is to the cannon. It is very fun to see what happens!
