You are the yellow rocket. Use the Left and Right arrows controls to move the ship, and use the space bar to fire rockets at them. There will be invaders in WHITE ships and if they get to the orange bar or touch you, you will lose a life. Occasionally, there will be extra ammo, which will give a random number of rockets between 1 to 5. When the ammo button on the left side of the screen flashes, you get the extra ammo. After you play the first time, it's time to get crazy!
If you look at mine, I added a combo shot encouragement message.
