Dean recalls: "This game was created at Video Images, a co-operative company formed in 1987 in Scunthorpe by David Bradley, David Colley and Dean Hickingbottom. The original CPC version was coded by David B. and Dean H. at Video Images. When the company split, Dave B and Dean took the game with them to Clockwize in 1989 and it was sold along with a ZX and CBM64 conversion (by Craig Wight), to another company. As far as I know it never saw the light of day. The company was Palmer Acoustics Ltd of Sheffield (possibly PAL Developments Ltd??)"
