Vein City is a puzzle game from The Butterfly Game Studio where the city itself has a heartbeat — it remembers its past and is trying to communicate. Cast as a civil engineer, your job is to solve the city's problems and bring it back to life.
Watch the stories unfolding in the city, then solve each problem by connecting two or more endpoints together — routing a path from src to snk.
Each puzzle asks you to connect two or more endpoints by drawing a path from src to snk across the grid.
The city has a memory and tries to communicate — narrative stories set up the problems you then solve as a civil engineer working to revive the city.
If Vein City's src-to-snk grid pathfinding is your thing, Arrow Exit Puzzle and Arrow Puzzle both deliver constrained grid-clearing logic that rewards careful planning. Arrows challenges you with directional chain puzzles wrapped in a moody stylized look, while Wood Blocks Jam routes colored blocks to matching gates with the same calm, methodical session pace.
