Just press Return / Enter to run my problem input, or paste your own in. It defaults to part 2, but you can click "Easy Mode" for part 1.
Then play interactively, or click the Taco to solve automatically (Solving is slow ~400s but 100x faster if you are using TurboWarp, you can click the button under the Taco of solving to switch to using a faster greedy heuristic instead of A* or pure Dijkstra search).
