Your spaceship has to avoid rocks that are hustling toward it. Luckily,we have a laser blaster to fire at the rocks.Use the up and down arrow keys to move the spaceship up and down.Use the space bar to fire a laser.Each time your spaceship fires a laser,a clone of it has been created.If a laser clone hits a rock, you get 100 points.But if a rock hits the spaceship,the game is over.
