On receiving Cavern Commander I was immediately surprised by the low price. How could such a game be good. This is very good although it gets a little repetitive.
The object of the game is to navigate the dangerous caves of the planet Hesikos. You have limited fuel so time is of the essence. You then land your cruiser on the subterranean landing pads. Here you refuel before taking off to attempt another death-defying journey. As well as missing jagged rocks you must avoid the poisonous gases floating around which can bring you to an untimely end.
Your cruiser is operated using the joystick. Graphics are good as are the sound effects. The only thing that irritates me is the poor choice of colours on some of the screns. One is shocking purple with a black background causing poor visibility. Thank goodness all the screens aren't similar or the game would be spoilt. There are two versions, a 16K version on side one, and a 32K version on side two. Go ahead and try this, at this price you cannot lose.
