Howard Ball coded the Atari ST version, and Neil Metcalfe and Howard made the necessary changes to make it work on the Amiga. Much of the original Atari ST 68000 code ported straight to the Amiga with no changes - only the machine-specific code such as sound, graphics, keyboard, disk drive handling code, etc. needed changing. Pete Lyon did the graphics. [Source: Howard Ball (Howie)]
 The Amiga version was released the week 20th-26th September 1988.
