I think the vibe was correct in this game, the bootup of pc and the lines of the old computer - really cool, it gave the right feel for a terminal operator. What I would do is since this currently requires so much writing, i would either:
a. make the commands clickable and visible, this way more thought goes into figuring things out rather then remembering commands and typing, or
b. do it like the real terminal does when pressing arrow key up/down we can go to our last commands, then removes the unnecessary typing when contacting different rooms
Good stuff, I didn't trust anyone. :)
