FoldCity

A 7x7 grid of road tiles stands between your busses and there estination. Tap tiles to rotate their connections and build a path from the green door to the teal door.

Every few seconds the city folds a full row or column shifts sideways with wraparound, scrambling your careful routes. An amber flash and arrow warn you which line moves and which way. You have seconds to react.

Walkers follow the right-hand wall. If they can't find a connected path in time, they give up and count as lost. Lose 10 and the city folds for good.
