It's a quite easy game, you just need to use the mouse to play. Use the mouse and click exactly at the ships/boats to prevent them from reaching your 2 islands. If you can destroy 50 ships/boats, you win! And if one of the ships/boats successfully reach any island, the game ends and you can click "Play again" for another try. Note that the number of enemy ships/boat will appear faster and faster after "Level Up".
