ECHO

ECHO is an original browser-based puzzle platformer built around one central idea: the player becomes their own cooperative partner. Each chamber asks the player to record a route, replay that route as a looping echo phantom, and then solve the rest of the puzzle while their past self keeps switches, pressure plates, and timing windows active. The result is a game that feels retro at first glance but relies on a distinctly modern mechanic built around recursion, timing, and self-coordination.

HOW TO PLAY

Goal: reach the glowing exit door in every chamber. The player begins by surveying the room, identifying what must stay active, and then recording one or more echo routes. Echoes replay automatically until the chamber is reset or the newest one is cancelled. Each chamber awards 1-3 stars based on completion speed.
