## Description

Reflect. Split. Connect.<br><br>ECHO is a minimalist logic puzzle about routing a signal. Place mirrors, angle them, and send the beam. It either reaches every receiver, or it shows you exactly where it went wrong.<br><br>No timers. No lives. No punishment. Just a board, a beam, and the quiet satisfaction of a route that finally clicks.<br><br>ROUTE THE SIGNAL<br>Tap an empty cell to place a mirror. Tap it again to rotate it. Press SEND and watch the beam travel, bounce and light up the receivers. Wrong route? Adjust and send again - nothing is lost.<br><br>THREE STARS, ONE OPTIMAL ROUTE<br>Finishing a level is easy. Finishing it in the fewest possible moves is the real game. Every level has a verified optimal solution, so three stars is always possible - and always earned.<br><br>MECHANICS THAT BUILD ON EACH OTHER<br>- Mirrors reflect the beam ninety degrees<br>- Blockers absorb it completely<br>- Splitters divide one beam into two<br>- Portals move the beam while keeping its direction<br>- One-way gates pass only a beam travelling their way<br>- Multi-hit receivers need charging from two directions<br>- Multiple emitters: two signals, one board<br><br>Each one is introduced on a board where it is the only thing you have to understand, then combined with everything before it.<br><br>36 HANDCRAFTED LEVELS<br>Three chapters, each teaching a new way to think about the beam. Every board is designed and verified - never randomly generated, never impossible.<br><br>DAILY ECHO<br>One special puzzle every day, the same board for everyone. Build a streak.<br><br>BUILT FOR SHORT SESSIONS<br>A level takes under a minute. The game remembers everything, works completely offline, and never asks you to sign in.<br><br>DESIGNED, NOT DECORATED<br>Dark background. One cyan line. Soft glow. No clutter, no pop-ups begging for attention, no fake urgency. Just a puzzle that respects your time and your screen.<br><br>Free to play, with an optional purchase to remove ads.
