Destroy as many asteroids as you can without colliding with one (immediate game over). Use the left and right arrows to turn the ship. Use the up arrow to activate the rocket booster. Use the space bar to fire. Use the z key for an emergency "destroy all" (-100 points). If your spaceship or an asteroid reaches the edge of the screen, it reappears on the opposite side of the screen. (In other words: beware the edges!) New asteroids drift into the belt from the right side of the screen.
Inspired by the popular Asteroids video game of the late 1970s.
