Instructions:
You can move the laser base using these controls on the keyboard:
Space Bar = Fire laser
Left Arrow = Move left
Right Arrow = Move right

If you hit the UFO, you're rewarded with a "mystery" bonus score. It's game over after 3 lives, or if the invaders overrun the barracks. And you only get one shot at a time, so make sure you hit that target!
