Įach level starts with a few large asteroids drifting in various directions on the screen. The player can also send the ship into hyperspace, causing it to disappear and reappear in a random location on the screen, at the risk of self-destructing or appearing on top of an asteroid. The ship eventually comes to a stop when not thrusting. Once the ship begins moving in a direction, it will continue in that direction for a time without player intervention unless the player applies thrust in a different direction.

The game is rendered on a vector display in a two-dimensional view that wraps around in both screen axes.Ī ship is surrounded by asteroids and a saucer.
