I really enjoyed playing this.
Although I didn't realise you could make multiple connections.
I only realised when I saw the screenshot!
So I sat there getting a really high score with minimal connections.
If I had started losing score I would have realised you needed to make more connections, so maybe make sure the player can't get maximum score with minimum connections.
When I played a second time and the map zoomed out, I couldn't zoom in fast enough so my score went to 0.
I think you should let the player have a bit of grace while they zoom in and get ready to go again.
Oh and a tiny visual thing but I would suggest you let the player zoom in, as I found clicking the network lines difficult, they are very thin.
Overall I enjoyed it and hope you keep developing! :)
