The game was conceived in 1981 by Malcolm Evans
, who wanted to find out what the ZX81 his wife offered him for his birthday could do. After founding J.K. Greye Software
with John K. Greye
, the game was released early in 1982 and quickly became a classic for the ZX81. In spring 1982, Evans founded his own company, New Generation Software
, and re-released the game along with further 3D and other games for the ZX81 and ZX Spectrum.
