Space Caverns

In this type-in BASIC game from Compute! magazine, the player takes control of a ship beset by an unfortunate set of circumstances. Not only is it trapped in a series of caverns (presumably in space), it’s also given a less-than-welcoming reception by the local residents – a rather unfriendly bunch of aliens. In each room, four of them will try to chase down your ship, and you’ll only have your forward-firing gun to get you by.
