|Use the keyboard controls described below to maneuver your ship, destroying as many
asteroids as you can while avoiding collision with them. Also watch for the flying
saucers armed with guided missiles.
If you warp into hyperspace, your ship will momentarily disappear then reappear on
another part of the screen, gradually fading in. During this time the ship is invulnerable.
Likewise, when your ship is destroyed, a new one will appear in the center of the
screen. You can still maneuver and fire during this time so if you are in imminent danger,
you have a couple of seconds to get out of it.
