You wake in the corridors of an abandoned asylum. Find your way out, room by room.

• Arrows/WASD (or the on-screen buttons on touch) to move and turn - Q/E also turn.
• Space, or click/tap a door, to open it.
• Explore the corridors and collect keys, shown in the HUD, to unlock the doors blocking your path.
• The ROOM counter tracks how far you've made it in.
• Find the way out to win - and listen carefully, the asylum isn't as empty as it seems.
