Pilot a ship through a drifting asteroid field, blasting rocks apart before they hit you.

• Arrow keys, WASD, or the on-screen buttons, to rotate and thrust.
• Space, or the fire button, to shoot.
• H, or the hyperspace button, teleports you to a random spot - short recharge after use.
• Large asteroids break into smaller, faster pieces when hit - clear the fragments too.
• A flying saucer wanders in and fires at you - shoot or ram it for a bonus.
• A derelict ship drifts by sometimes - shoot or ram it for points and an extra line of fire.
• Flying off one edge brings you back on the other.
• Clear the field to advance to a busier level.
