Tommy Daffin of South Breham. Somerset, has converted Neutron Maze. It was origionaly written for the BBC Micro by a pal of his , P Dixon. I have not seen the Beeb version so I can't tell you if it has fared well en route. What I can tell you, though, is that I haven't seen a game like this before. It is original , fun and to a certain extent addictive - even Bob returned for another go.
The idea is to guide an electron through a Neutron fence using two keys: the spacebar and Return (or Enter). The spacebar causes the electron to change its vertical direction. Return alters the electron's horizontal movement. Before you start you are given the choice of start-level (1 to 10). Hardest level is 1 and easiest is 10. Stay sane and choose levets above 6. All other instructions you need or don't need are contained within the Listing.
