The more people developing for the wonderful Vic 20 the better. Great game, mate. Well done.
What dev system did you use to program it?
CBM Prg studio is great for development at assembler level for Commodore machines. If you ever want to try doing it in a bit more user-friendly language then perhaps have a look at TRSE. It's fantastic for working on Vic or C64 games :)
