Super well done! All of the elements work really well together and it's all communicated really well to the player. I especially like the instructions being written on scraps of paper, as if they're being left for you by some passive aggressive office worker.
The one problem I had was that the font choice made me confuse the D in FWD with and O. And there was so little time to experiment with that command before the enemy kills you that I didn't type it in fast enough when I figured it out.
