Played this game for far longer then I'd like to admit. It beautifully mends a simplistic design with long term strategy. The responsive music was a very nice touch.
My only complaint is that long term the game's difficulty curve completely falls off and you just run out of stuff to do. I was able to get everything max upgraded then just kinda stopped as there was nothing else to do. Ended up destroying my network just to see my highscore (it was 588,480).
If you wanted to keep working on it (which I would love to see you do) I suggest breaking the game up into several levels that provide unique challenges such as deadzones where connections can't be made or the archive where every message must also be sent.
Overall a fantastic game and my favorite of the jam so far. Great work!
