Navigate a pitch-black maze by sonar. Pulse, listen, find the way out.
The screen is black. You can't see the walls — you can only hear them. Echo is a maze game unlike any other: a game of sonar, sound, and nerve. Send out a pulse and the walls around you light up for a heartbeat, then the dark takes them back. Between pulses you swim blind, listening for the amber beacon that marks the way out — and for the low hum of the hazards hunting you in the black. HOW TO PLAY • Drag anywhere to swim — no on-screen stick, just your thumb. • Tap to send a sonar pulse. Walls glow, then fade over about two seconds. • Follow the amber beacon to the exit and descend to the next depth. • Red pulses are hazards, not the way out. You have three lives. WHY PLAYERS LOVE IT • A maze in total darkness — pure navigation by sound and light. • Procedurally generated: every depth is a new maze, endlessly. • Directional, distance-aware audio — you can hear where the exit is. • Minimal, moody, one-handed — made for a quiet moment or a tense one. • Four unlockable colour palettes: Sonar, Bioluminescence, Ember, Ultraviolet. • No forced ads mid-dive. No banners. Watch a rewarded video only if you want to. How deep can you go before the dark swallows you? Dive in. Echo is a small, handcrafted game from sainilabs. Works offline. No accounts.
