Aaah this is superb. Thank you Peter! I often remember this game, it's a sublime memory. I come back to it on emulators sometimes but still can't get far. I guess that keeps the mystery of it still going though. Cheers.

Hopefully you scan in his notes for the archive. I would like to know how he actually programmed it in did he use an assembler or was it all in basic. Also his workflow, like did he first get basic framework gong then expanded on it bit by bit?
