The tutorials reminded me of my applied netcentric computing class. Playing around with my fedora server using just the terminal was a favorite past time of mine. The system is pretty easy to learn and the tutorial being a sepparate module really comes in handy if you need a refresher. I really look forward to future versions of this game. This looks to me like it could become the hacker game I've been hoping for.
I'm bad at finding bugs, so I may not have much useful input to offer.
