There are a few hallmarks to Trust Fall that were important for me to keep. Individuals are given a lot of power in this setup, and one wrong read from one town player can make or break the game. Simultaneously, I think Koba throwing/trolling the previous iteration exposed that one town player can singularly strip away the decisionmaking of the entire game by multitrusting. Some suggestions to make other town "approve" trusts I felt were antithetical to the spirit of the setup, which empowers the individual.
The idea behind "one offer per player" was to keep that individual power/decisionmaking without letting any one person seize complete mechanical control of the game. I think it worked out well, but I'm open to feedback.
