A PUZZLE ABOUT YOU. AND YOU.

Second Self.

A little help from who you used to be.

Leave an echo of your footsteps. Let your past self hold a door while you find another way. A growing collection of chambers about learning to be in two places at once.

01

Take a few steps.
Your route is recorded as you walk.

02

Make an echo.
Go back. Leave your footsteps behind.

03

Find a way together.
Your past self moves when you do.

No clock. No penalty for undo. Just an idea to try.

How time works here

Every move is a turn. Your echoes take one step whenever you walk or wait. A blocked move does not advance time.

A recording starts over. Make an echo to return to the start. All echoes begin their routes again, and collected lights return. Echoes can pass through closed doors and each other.

A door checks who is on its plates now. The symbols on each door match its plates. Once your echo finishes walking, it stays on its last tile. You can leave a door if it closes around you.

Undo is always allowed. It reverses the whole last action, including making an echo. Match the turn target for three stars. Targets are known solutions, so you may find better ones.
