I've been thinking sequel ideas lately. If I do one, I'd want it to be an expanded experience. I'm not sur yet if it would be a sequel with the same characters or more a sequel to the game's basic concept but with different characters.
I had a few ideas for additional installments, but haven't done any yet. One idea was going to be like a welcome CD for a 90s PC kind of thing. Or an 80's ASCII RPG.
