ECHO

Reveal the unseen.

Echo is a minimalist puzzle of sound waves. Tap to send a wave that ripples across the screen — when it touches a hidden object, it reveals itself in light.

Your goal: find every hidden object using as few echoes as possible.

✦ Infinite procedurally generated levels

✦ Pure monochrome aesthetic — black and electric cyan

✦ Soft ambient audio that responds to your touch

✦ Mobile-friendly, no downloads, no accounts

✦ A meditative challenge for moments of quiet focus

Each level is unique. Each echo is a question. Each reveal is an answer.

How clearly can you listen?
