This is a lot of fun. Is the D6 roll in the room creation section there to decide the order for the players to describe the rooms? It might also be nice to give an example of one round of play for players who are not used to this kind of rules-light game, especially when it comes to finding/destroying evidence, as the process for that isn't 100% clear at first read. I'm assuming Perception roll against a certain DC? A really intriguing system here.
