Use the left and right arrow keys to move your spaceship side to side. Click anywhere with the mouse to shoot. Remember, you have to click beyond the alien to shoot it. Otherwise, the shot will come short. Do not let the alien reach Earth. It will destroy Earth and you will lose. To win, you have to blast 50 aliens. Have fun!
