Solve itwith yourself.

A puzzle game where the only other player is a recording of you. Record a route, and it becomes an echo that repeats it forever. Stand where someone needs to stand — then step away and be somewhere else.

The First Echo

Record, then step away

Tap RECORD, walk a route, tap STOP. That route becomes an echo, and it replays the same twelve seconds for as long as the chamber runs.

The opening chamber is one plate and one door: the door holds open only while something rests on the plate. Here the echo is the one standing there, and the door ahead of it is open.

Three Hands of Time

Cyan, blue, violet

Up to three echoes run together, each a generation older than the last, each in its own colour — so you can tell at a glance which loop is which.

This chamber has three mechanisms and wants all of them held at once, so each echo takes one and you keep clear. The counter reads 3 / 3; that is the ceiling.

Three Hands of Time: three echoes spread across the chamber, one on each mechanism, counter reading three of three

Twin Pressure

Two plates, two hands

Some doors want more weight than one body can give. This chamber has a plate on either side, and both have to stay down at the same moment.

That is two recordings that have to overlap — and you free to walk through while they do.

Lantern Passage

Light you have to carry

This chamber is not fully lit. A band of shadow lies across the middle of the room, and while it is dark it is solid — you cannot walk through it.

The lamp clears it, but the lamp only works while a plate stays held down. So one echo holds the plate, another holds the lamp, and the way opens.

Eleven chambers

One trail, opened in order

Finishing a chamber opens the next one along the trail. Undo removes your most recent echo without restarting the room, so one mistimed route costs you one recording and nothing else.
