Echo: Time Loop Logic Puzzle

Echo is a time loop logic puzzle where your past selves are your teammates. You can't hold the door and walk through it. Your past self can.

In this time loop game, every move is one tick of time. Tap LOOP and time rewinds: your last run becomes an echo that repeats your moves exactly while you play again. Send one echo to stand on a plate, another to open the next door, then walk through yourself. Several of you, one plan, perfect timing. It's a brain puzzle about planning, not reflexes.

SEE TIME AT A GLANCE
- A tape timeline shows every echo's recorded moves and where the clock is now
- Each echo shows its upcoming path and where it will be on the next tick
- Wires, colors and symbols show which plate opens which door

LEARN BY DOING
- The first levels guide you with a hand on the exact tile or button
- Every new tile is introduced the same way: twin locks, striped doors, one-way tiles, echo relays and three-echo puzzles
- Undo any move, even a whole loop

160 TIME LOOP PUZZLES IN 8 LABS
- A timeline map from Calibration Lab to the Omega Loop
- Every puzzle is checked by a solver; par echoes and par ticks are exact
- Three stars per level: solve it, use the fewest echoes, finish in par time
- Breather levels between the hard ones and a boss at the end of each lab
