The first game to feature Incentive’s incredible proprietary game engine Freescape, but oddly not the first one I purchased (that honour goes to its sequel, Dark Side).
An incredible achievement on 8-bit computers back in 1987, even if the screen update was 1 fps. A first person adventure well ahead of its time, crammed in to a computer with a clock speed of just around 1mhz and only 64K of RAM.
