Causal Echo

Causal Echo is a turn-based sci-fi puzzle game about memory, causality, and cooperation with your recorded past.

First, record a route through the level. Then replay beside your Echo while both timelines activate linked devices, open gates, and reach their anchors on the exact same beat. Every move matters: running out of steps, breaking the recorded route, or trapping either character causes the timeline to collapse.
