You sit in one room from 12 AM to 6 AM. You cannot leave, and you cannot fight. You have doors, two lights, a camera tablet, and a battery that will not last the night if you waste it.

Controls

On touch: use the buttons along the bottom, tap a room on the map, and drag a camera feed to look around it.

Who's in the house

Power

Everything costs battery. Sitting still is one usage bar; each closed door, each lit doorway and the raised tablet add another. Four bars will not survive the night. At 0% the doors fall open, the lights die, and you are left in the dark with whatever is already in the hall.
