Thank you so much for the feedback!
Hmm, that might have been a bug, as computers should never stop appearing. The idea is that the camera zooms out more and more as the network grows, so you have to keep an eye out for any computer that wants to connect. Although the scaling got a bit off due to lack of playtesting the later stages. In my original idea you would be dealing with regions in the endgame, but I had to scrap that for time and it became a "look for buggy connections around the globe".
