[Witch of Uncertainty]

I got it myself. Can read the Rules for you:

Spoiler for Killers Gambit::

Roles:
Storyteller: Guides the progression of the game, and cannot be killed.
Killer: (3 players) Each turn, choses a player to kill.
Caretaker: (1 player) Each turn choses one player to protect
Observer: Each turn, chooses a player as a suspected killer.
Innocent: (Rest of the players) - Each turn, vote on who they think the killer is, and remove them from the game.

Goal:
The killer wants to remove everyone else from the game. Everyone else wants to find the killer and remove them from the game.

Setup:
One person assumes the role of Storytelleer and Shuffles the deck, then hands one card facedown to each player. The players may not reveal their card to any other player. The game begins with the Storyteller telling all other players to close their eyes. This begins the "Night phase"

Night phase:
The storyteller directs the killer(s) to open their eyes, and they choose one player to remove from the game. The killer(s) then close their eyes. Next, the caretaker chooses one player to protect, and they may select themselves.
Next, the Observer points to the person they think is the killer, and the Storyteller must silently confirm or deny their choice. Once the observer closes their eyes, this ends the Night phase.

Day phase:
The storyteller directs everyone to open their eyes. If the Killer(s) and the Caretaker selected the same person, the Storyteller must announce that nobody died, with no further detail, and the targeted person stays in the game. Otherwise, the Storyteller announces who died (without revealing any clues about the identity of the Killer(s), Caretaker or Observer). The "Dead" player may not participate in any phase of the game from that point.
The remaining players then debate who they think the Killer(s) is, and vote to kill another player.
Once a player is removed by simple majority vote, the Night phase begins again.
The roles of killed players should not be revealed unless it results the end of the game.
