Your goal in the game is to shoot your opponent. The system gives you the right to shoot one at a time and one to your opponent. When it's your turn, determine the direction to launch the missile with the mouse or by touching the screen and shoot. When you try, the missile you throw will start to bounce by hitting the obstacles on the screen and if the missile hits your opponent, you will win. Just see the white arrow on the back of the player to see which player is yours. When you play a little, you will see that it is a very fun game after a while.
