Cooke's games were often innovative. For example, Tau Ceti (released 1985) featured a form of solid 3D graphics but was also set on a planet with day and night cycles with dynamically drawn shadows. Micronaut One (released 1987) was set inside futuristic biocomputers with the player controlling a microscopic craft attempting to clear the tunnels of an insect-like life form called Scrim. This game also used fast-moving 3D graphics as well as featuring an enemy that went through a realistic (if speeded-up) life-cycle, beginning each level as eggs and progressing to larvae and eventually adult Scrim which would then lay more eggs. Even Cooke's more straightforward games, like the 1988 shoot 'em up Earthlight, featured their own complexities and technical gimmicks.
