Closet of Mystery

This game is perhaps the shortest in the PunyInform jam, and it isn't perfect, but it has a lot of distinct advantage over its competitors:

-it has an overarching narrative
-it fits several twists into a 3-move game
-most objects are implemented more than the other games implement their objects

As surprise is the main feature of the game, I suppose I won't say much more. You start in a pub broom closet with a knife holding a note onto the wall.
