Twists from the well-known Werewolf game:
1\ The dead ones can return to the game as the operator of Ouija (if they can beat up all other dead spirits). If the Ouija leads to a meaningful result, the debate section will be just skipped.
That means, the dead person can kill. XD
2\ The game has a Ouija section in every turn, which can lead to really funny body contacts.
For me, the most funny experience in a party werewolf game is not the logical deductions and debates, it's the accidents and external or physical hints.
3\ No innocent villigers. Everyone is here to kill.
That is me trying to give everyone a reason to disturb the ouija.
