Thanks for playing :) We both 100% agree with getting command history with arrow keys, and we even planned adding it - but just got cut due to time. Time speeding up is a great shout, haven't thought about that. We planned on having different commands installable to different agents to allow them to specialise, but we ran out of time :(
Its definitely a niche kind of game, and some play testers didn't 'get it' but they appreciated the vibe, if we develop it further after the Jam we would explore alot more into the usability of the terminal.
