Space Caverns

Your diamond ship is trapped in a walled cavern with four homing aliens worth 50 to 200 points. Clear them to reach the next room, and after enough rooms comes a bonus round of sleeping aliens paying whatever the countdown shows. Later levels shrink the caverns and start you inside crystal rock, which your laser cuts but the aliens simply fly over. An extra ship comes at 10,000 points.

Controls: The stick moves; the button fires the way it last pointed.
