A collaborative improvisational freeform storygame framework for a flexible amount of players, possible to play within whatever amount of time they have available. A group of players get together and sketch the game they want to play, then do it.

The player in charge of the scene decides which characters will be present in the scene and when it's time to end it. (S)he can also act as director, asking players for inner monologues, introducing characters etc. (S)he can also be a player in the scene. Try to remember what has happened in previous scenes, and re-incorporate elements from them.
