Jonathan recalls: "This game actually made it to the C64. I vaguely recall Jim mentioning this 2 or 3 times over the telephone (among many other potential projects he mentioned as I can think of at least 2 others), and I know I was busy doing Grand Prix Drivers at the time so there almost certainly won't be any remnant of code for this on any of my old tapes. This is probably just speculation, but I just wonder if Jim Scott actually approached any other Spectrum developers with this conversion back in the day, and would anybody have done any work on such a title?"
