Echo

You are a faint spark of light, lost in a pitch-black maze. You cannot see the walls. But you can listen. (And NO Ads)

Tap to send out a ping. The echo races down the corridors and lights the walls for a moment, then the dark closes in again. Remember the shape, find every shard, and reach the exit.

The catch: you are not alone. The creatures down here are blind, and they hunt by sound. Every ping you make, every running footstep, tells them where you are.

QUIET OR LOUD — YOUR CHOICE
• Tap for a quiet ping that shows the walls close by.
• Hold for a loud ping that floods far down the halls and is heard far away.
• Walk silently, or run and make noise. Every move is a gamble.

BLIND CREATURES THAT HUNT BY SOUND
• Drifters wander toward the last sound they heard.
• Stalkers are faster than you, but only wake for loud pings.
• Sleepers lie still until a noise happens close by. Then they lunge.
• Mimics send out fake pings that show walls that are not really there.
Creatures flash red when your echo passes over them, and your phone beats like a heart when one gets close.

MAZES THAT FIGHT BACK
Every level is a new layout, built so you always have a way to slip past. As you go deeper, the mazes get stranger:
• Multi-floor mazes joined by stairs, with shards spread across every floor
• Glass walls that block you but let sound through
• Curtains that swallow your pings, and water that silences your steps
• Echo chambers that light up a whole room, at a price
• One-way doors, crumbling floor tiles, levers that open sealed vaults
• Shifting walls that slide every 30 seconds, so the map you remember goes stale
• Hidden cubicles where nothing can hear you

TOOLS AND POWER-UPS
Throw stones to make a decoy noise, or hit a creature to stun it. Pick up nine power-ups, including Sonar Blast, Echo Memory, Sprint, Compass, Heart Sense, Ghost, Quiet, Decoys and Traps. Turn any of them off in Settings for a purer challenge.

WAYS TO PLAY
• A 30-level campaign that teaches each new idea, one at a time
• Easy, Medium and Hard modes with endless levels that grow in size and danger
• A Daily Challenge: one maze, the same for everyone, one attempt a day
• Google Play Games leaderboards for Easy, Medium, Hard and the Daily
• Switch between a top-down view and a first-person 3D view at any time

MAKE IT YOURS
Choose your light from eight characters, from the classic Wisp to a cute Bat Pup, a warm Lantern or a glowing Firefly. Pick your wall colour, how long echoes glow, and how quickly your ping recharges.

PLAY WITH HEADPHONES
Every sound is positioned around you. With headphones, you can hear exactly where a creature is: left or right, ahead or behind. Close your eyes for a second and listen.
