MOVE with WASD or the stick. You drift through walls; the tenant does not.
RIG an object with E. It takes 1.5 seconds and you are visible the whole time, so pick your moment. Every armed trap gets a glowing tell so you can read the room.
POSSESS with F to rattle a chair, flick a switch, wind a music box. It drains Spook and it drags the tenant toward the noise, which is how you steer them into a trap.
HIDE with Space next to a wardrobe, a bed, a clock. Concealed, your Suspicion drains fast and your Spook refills.
WAIT with Q to run the clock forward. Traps only fire when someone walks into them, so timing is the whole puzzle.
FEAR fills to win. SUSPICION maxing out loses. Be too subtle and Fear drains; be too loud and Suspicion spikes. Escalate at the right pace.
