"The game was written for HMV (the one close to Oxford Circus) when they first started selling games. Their game "shop" was called Level1 and they required a game which people could play in their store. So, we took the Fire & Ice game and stripped it down to this. It took about a month to do from start to finish.
The game was then unveiled at the Level1 opening night, where people got to play it. It crashed once but the bug was fixed for the cover disk release. (It was a problem where you could kick cats out of the side of the level, so that they would then be dropping pickups throughout your game code... oops!)
I was shit at this game, by the way... And was amazed that people could get such high scores. It was not a demo of a full game - it was just a short "game" which people were meant to be allowed to play in the shop.
Oh, and Dexter Fletcher (the crappier presenter of Games Master) was one of the guests on the opening night. But he got chucked out for trying to nick games off the shelves! Actually, it was *really* stupid of HMV to hold a party with drink and food at their store! People were hiding unfinished cans and food behind the ST games... hehe...
Oh, and there's also another "secret" Graftgold game which is similar to this one, which I wrote for PowerGen (the electrics company). You had to do pretty much the same thing - with different graphics... It was for their own internal promotion, so never saw the light of day outside of their company and would only have been played by kids on school trips to nuclear power plants or something... unfortunately."
