There's an article about this in ACE magazine number 48 (September 1991), where Molyneux explains all his (pretty stupid, IMHO) ideas for the game.
As he designed it, it wouldn't have been a game I want to play, but the graphics would have been gorgeous, I love that 'cutesy' style (you don't really see this style much, at least done in these hand-pixelled, juicy lores pixels).
Here are the pictures from that article:
Could've been an interesting game, but I think his ideas were just so incredibly badly thought-out, I didn't like almost any of them.
However, I hope someone revives that cutesy pixel style for some other game, demo or whatnot (I am planning to make a similarly styled, but closer to 'Spy Hunter' graphics type 'screensaver' with traffic going back and forth and reacting to itself), and creates something exciting with it.
