GhostLoop

GHOST LOOP is a temporal spatial puzzle about routing energy through four overlapping timelines without letting the past collide with itself.

How it works

Each level is a grid studded with obstacles and pairs of terminals — a filled circle to depart from, a glowing ring to reach. You record one path per time phase: drag along the grid, tap adjacent tiles, or use WASD and the arrow keys.

Once a route reaches its destination, hit RUN PHASE. That path locks in and the simulation begins — every previously locked phase replays at the same time, all four sparks stepping tick by tick.

Avoid paradoxes

Two sparks sharing the same tile on the same tick creates a paradox. So does two sparks swapping adjacent tiles simultaneously. Either one collapses the loop. Plan the timing of every phase, not just the route.
