Your past is the way forward.

Alone in an abandoned factory, a robot has one unusual advantage: its echoes.

In ECO, every attempt can become a replay of your actions. Record your movements, then work alongside your past selves to hold switches, open doors, and reach places you couldn’t reach alone. Sometimes, the next step is literally on an echo’s head.

Explore 20 increasingly challenging levels filled with narrow platforms, dangerous gaps, and puzzles that demand careful planning. Build towers of echoes, change direction, and rethink your route when a plan falls apart.

You can keep up to four echoes at once. Make every recording count.

Features

• A single-player puzzle platformer built around replaying your own actions.

• English and Brazilian Portuguese language options.

• T: Clear all echoes and start fresh
