Fun little game. I had a problem in the first level where BOB was corrupting non visible links. Had to play a bit more to then understand the goal correctly. I support the idea of having a dezoom at some point to see the map globally.

Very nice visuals. It took me a while to actually understand it and I'd like to suggest that, after you lose a match, it would let you hover the camera over the "board" to let you see what it was like when you lost. As a slow learner, being able to look directly at my mistake helps figuring out what I was doing wrong. Bob is trying to ruin the internet, huh? Defense! Defense! Defense!

It's short but fun, not much to say with how simple it is

That was fun!  I played as both Alice and Bob.  I liked the steps of play and counter-play.  Not sure that the underlying mathematical structure is rich enough to support a full game (although I've not looked up shannon's results, so if the question of whether A or B wins is NP-complete, then maybe it is!).  My immediate thought is that this could be great as a strategic layer to some other game, so that even if you know what the optimal Bob-move is you still have to weigh up whether that's the connection you want to try and cut?  Just spitballing.

I like the aesthetics, but it's a pity to have to scroll around to see the whole network.  Nice game, anon!
