Defend against the green aliens trying to reach the end of the screen, each alien you kill awards you coins (not visible in game but accumulate in background) which you can spend on building and up grading towers on the 11 floating islands. the towers you build will shoot homing bullets at the aliens to stop them in their path but be careful green aliens attack in large numbers and are ready to fight to death!
