Swibble Dibble

This game is little-known outside of Germany (which is, AFAIK, the only country it was officially released in), to the point that when someone sent a tip for it into Amiga Power magazine, their writers assumed that the game didn't exist and had been made up. Around a year later, someone sent in a tip for 'Swibble Dibble 2' (which doesn't appear to exist, although many cheat sites carry the cheat in question), presumably as a joke.
