I did enjoy Hacknet and Uplink back in the day, but I'm afraid that my collapsing brain simply crumpled under the intellectual weight required by this game. I set :impcon's host, hit exploit, failed the set_host test. After a couple of alternate hosts in list, I was about out of ideas. I also happened upon a couple of crashes after running :impcon config, so maybe my computer is just full of termites.
For actual, tangible feedback that doesn't amount to "please pander to my 70 IQ", the bright gridlines distract from the server icons in the map. Fun to mess with the terminal, though. Good luck with the game.
