You can't see the room, you can only listen to it, and so can the things hunting you.

How to play
Every level is total darkness. Throwing a rock cracks against a wall and briefly lights the shape of the room around the impact, like sonar. The catch: the same noise draws blind predators that home in on whatever they hear. Pick a path to the exit, ping just enough to find your way, and never make a sound you don't need to make.
Reach each level's exit to descend deeper; the run is an endless survival ladder and your score is how far down you get.
Rocks are limited, collect more from the floor and don't waste them.
Footsteps make noise too, so moving carelessly can give you away.
Get touched by a hunter and the run ends.
Controls
Desktop: tap/click a spot to walk there; press-and-hold to throw a rock toward that point. Press the Pulse button (or P / Space) for a sonar blast that stuns nearby hunters but screams your position. Keys 1–4 audition creature voices, 0 resets, M mutes, H toggles haptics.
Phone & tablet: fully touch-playable, tap to move, hold to throw, tap Pulse to blast; supported devices also rumble as danger closes in.
Tips & strategy
Throw rocks ahead of you, not at your feet, light the path you're about to take.
Save the Pulse for emergencies: it stuns a closing hunter but its loud blast can pull others toward you.
When a hunter is actively chasing, freeze and go quiet; many will lose your trail if you stop making sound.
Grab rock pickups whenever they're on the way; running out leaves you nearly blind.
