Space Adventure (1988)

A conversion of a 1983 BBC Micro game that plays a bit like a more complex version of Berzerk. The goal is to traverse a ship, grab keys, power packs, and destroy robots. The goal is to find remove all 4 crystals, which require keys. Removing all 4 crystals cause a chain reaction to destroy the ship while power packs allow you to recharge your life support, phaser, and blaster. Pretty fun for what it is.
