did you publish it? i'd love to try it out.
Alas, the UI features weren't quite up to the task back when I made the attempt. They may be nowadays, but I can't imagine diving back into it. The far easier solution was to give everyone a hidden zone, a pawn and two index cards (Character and Hidden Asset). We keep giant index cards at the end of the table for the pros/cons of the location, tarot cards for dealing, and a whiteboard flat on the table for roughing the area out in marker. It's made for at least 100 hours of improv shenanigans with friends!
(Bonus: Keep a d20 on hand for handling character disputes with "highest wins")
