Welcome to Moon Attack! How to Play: You are on the moon with very limited oxygen. Try to collect as many oxygen barrels as possible (by touching them) while shooting the asteroids that come your way by clicking them. Press Z to jump. Oxygen barrels give you 5 extra oxygen along with +3 maximum oxygen. If you bump into an asteroid, you will lose 1 oxygen. Click asteroids to shoot them for points or oxygen. UFOs are worth 250 points if you get one of those. Click missiles to stop them and get 25 points. If you do not stop them in time, you will lose 500 points and 5 maximum oxygen. Run out of oxygen and you lose. There is a boss every 5000 points.
