The player can thrust forwards or backwards using the up and down arrows, and turn rotate the ship with the left and right arrows. Shoot plasma balls to explode the asteroids with spacebar.


The goal is to destroy all 10 asteroids, but they will split into smaller ones, eventually disintegrating into nothing.

By pressing 'c', players can increase the difficulty making the arena circular, reducing the size of the arena, and the asteroids bouncing around the circumference of the circle.

If the player runs into an asteroid, they explode. They have 3 lives to get the highest score they can.
