You died, or so you thought. Your soul is trapped in a liminal haunted house until you can satisfy five otherworldly entities. They don't want money. They want screams, laughter, vomit, and mind shards from the living.

Orchestrate your operation room by room. Place traps where the flow of guests is heaviest. Chain together scares, laughs, and gore for bonus resources. Where the house falls short, do the scaring yourself with a variety of supernatural spells.

Manage a team of creatures each with a personality, skill set, and needs of their own. They are not easy, but they get the job done. Experiment to find where they are most useful. Oh — and they may occasionally slay a customer.

Five supernatural entities, the Patrons, keep you in Limbo. They each want a specific resource from the living. Fulfill their requests, and they'll help you plan an escape. Or you may just end up liking them enough to stay.

Screams, vomit, laughter, mind shards: all raw material. You must compress them, combine them, and refine them into products of increasing absurdity.
"Accidents" happen, right? Guest deaths attract attention, some of it warranted, but always unwanted. You'll need to dispose of any bodies before the Bureau of Liminality catches on. Otherwise you may have to sweet talk them. How you handle the Bureau determines how much time you have.
