I really like the idea of the shell type game but I would have also added an in-game UI (as a wildcard). While I would want to use the commands for drilling, navigating and crafting, I would have liked also a live feed of what's happening with heat, power, cargo. Maybe a section/screen with ASCII art above the console; the time-frame is kind of tight and it's good for keeping the pressure, but the print/echo commands get in the way a little too much. I love the atmosphere, and the type of scenario.
