Lie to me Darling
We did a HatJam where the theme was "fairy tales". We picked up Pinocchio out of a hat and decided to create a lying simulator. Pinocchio has to kill villagers by lying. When he lies, his nose grows and pierces the villagers. It is an instant kill but the blood gets nasty and Pinochhio's appearance becomes dirtier. Hence he is suspicious for the guards protecting the city. When he tells the truth, the villagers kiss him and he gets all cleaned up. He has to survive in a certain amount of time, balancing his needs of killing and his necessity of discretion.
