Lucky Twin Echo

A puzzle game where the only other player is a recording of you. Each round lasts twelve seconds. Record a route, tap stop, and it becomes an echo that repeats forever. Stand where someone needs to stand, then step away and be elsewhere. Up to three echoes at once, in cyan, blue and violet. Plates need weight held down. Levers and wheels need a hand at the right moment. A door opened by an echo on a plate stays open only as long as it waits. Eleven chambers, each with its own layout. A bridge that extends only while someone holds the lever behind you. A lamp carried into a shadowed corridor to make it walkable. A mirror that turns a beam into the door controller. A filter that ignores your first echo and answers only to a later one. Two mechanisms live for two and a half seconds each, so the window where they overlap is the whole puzzle. A clock core that opens the last door only if plate, lever, wheel and core wake in that order. If a chamber looks impossible, watch one full loop before recording. What blocks you is usually a detail on the board, not a limit on what you may do. Undo removes your last echo without restarting the chamber, so a mistimed route costs one recording and nothing else. No accounts, no ads, nothing to buy, no network requests. One save on your own device.
