You are in the dark. You cannot see the walls. Feel your way out.
Walk with arrows / WASD, the on-screen D-pad, or swipe. Bumping a wall stops you with a thud. A faint glow shows only where you stand. The tone gets higher & faster as you near the exit — lower as you stray. Tap PING for an echo that briefly reveals nearby walls.
Reach the exit across 3 mazes. Headphones recommended.
