Several days ago, something reminded me of an old game that I played on my Windows 95 or 98 computer. The closest game I found online is this. Concept-wise, it's the same, but the graphics were much better in the one that I played.

Anyway, I decided to create my own version. Here it is. I used AI to create the graph building algorithm. I don't plan to maintain it, it works fine for a one-off experiment like this.
