Mind Walk

Mind Walker is a video game written by Bill Williams and published by Commodore in 1986 as one of the first games for the new Amiga 1000 computer. The player is immersed inside a human brain and must cure a psychosis that is threatening the patient's well-being. Many aspects of the game (including enemies and power-ups) play on this psychological theme. The four player avatars, for instance, are the human bodybuilder, the water nymph, the mysterious wizard, and the alien spriggan. Only one version of Mind Walker was released for the Amiga. This single version continued to run without problem across four generations of operating system, three generations of CPU, and at least three generations of platform hardware, spanning over six years.
