Transit Line Mapper

Transit Line Mapper is a 60 FPS minimalist subway network planner set
across three river metropolises.

Drag color-coded octilinear rail lines between emerging geometric
stations, route underwater tunnels across winding rivers, deploy trains
and passenger carriages, and upgrade busy transfer stations into high-
capacity interchange hubs to prevent platform overcrowding.

Features:
- 60 FPS octilinear subway mapping, underwater river tunnels, and loop lines
- Multi-line BFS passenger transfer routing and real-time fleet dispatch
- 3 river cities (Thamesbend Basin, Twin Fork Harbor, Archipelago Delta)
- 3 difficulty modes (Casual, Arcade, Turbo), WAV audio, JSON history, CSV export, EN/VI UI
