Mt. Holly has forty-five rooms on the plan and a persistent rumour about a forty-sixth. Getting there is a puzzle, and the house is not going to sit still while you solve it.

You choose what is behind the door

Reach a closed door and you draft the room that appears behind it. Every pick shapes the run, every room brings its own puzzle, and a good layout is something you build rather than find.

Days that reset

At dawn the floor plan wipes and you start again. Only permanent upgrades to the estate carry over, so a day spent finding one is worth more than a day spent getting deep.

Worth taking notes

The house rewards paying attention across runs rather than within them. Players who keep a notebook get further than players who do not, and the game knows it.
