The Fool in this game doesn't correspond to Fool from Throne of Lies or Jester from Town of Salem. It's actually Random Cop from MafiaScum, but Fool definitely makes more sense. It's funnier too :)
The link for Traitor actually points to the page for Seer, btw.
I haven't gotten to play this with anyone, but it looks really well-made. I noticed this is the second version. Really good job!
