Very cool game, does well to create the atmosphere and world building with small details and interactions, enjoyed it a lot!
My only suggestion would be to add a cmd history feature to allow you to press the 'up' key to 'paste' the last entered command into the current input line. similar to how cmd.exe works. just a small quality of life bonus :)
Thanks for making the game, and keeping text based games alive!
Also potential bug:
I had the spare arm but could not pickup a second weapon, unless I dropped the shield first, then I could carry 2 weapons and the shield.
