Thanks for the feedback, and I'm glad you enjoyed playing. I thought about adding the auto complete, but decided not to because I felt that some of the funnest/most exhilarating moments happened when you made it through a gauntlet by typing the correct commands barely in time. Also, from what I remember of Hacknet, a lot of the commands are obnoxiously long IP addresses and such, so I don't feel its as necessary, but that's just me. As for the case sensitive commands, that was totally my bad, all commands need to be lowercase in order to work.
Thanks again for playing!
