Object of the Game
You must shoot all the moving targets.
Press the left and right arrow keys to move your ship. Press the spacebar to shoot. If a target is hit, it becomes a wall, making it harder to shoot the other targets. (Be careful! You have limited bullets!) As you move along you will find many different kinds of targets.
When the orange block mechanism is introduced, the ship still moves around on the instruction page. Shoot everything you can on the page explaining the orange blocks. This will take you to the 3 secret levels.
