I love hacking themed games, but as IRL dev and ex unix admin I can be too critical to terminal QOL.
And sorry for my English...
Some feedback:
1) command like home to return back to own server must have.
2) you have limited commands make server names also autocomplete or use shortcuts also looks must have for me.
3) game feels too slow for current number of features.
4) If You added "IRL" camera to game. It's cool if its shows activity for currently mining server. (or its already implemented and I just missing?)
Try first steps in BitBurner if you don't.
Terminal good in first place for his scripting features and modern terminals also good for hotkeys and autocomplete. If You don't implement any of it buttons looks better.
