Thank you for all the kind words! Only "k" working is not a bug! You'll have to play through until level 2, where you can activate "bottom thrusters" by pressing space against the console in the middle of the room. (The Captain is trying to tell you this when he says 'only the bottom thrusters are online' but it probably gets lost in the text wall)
I'll put more in the dialogue and description to make this clear
