Night Courier од mle256841

Plan a tiny after-dark delivery. The courier starts by traveling east and changes direction at signs you place on the road. Click a square to cycle its arrow, then press Send Courier to see the route. A blocked route can be adjusted and sent again without penalty. Five fixed, solvable deliveries give this compact puzzle a clear beginning and ending. Progress is stored locally; the add-on stays entirely inside its popup and works offline.
