This is really cool! Really interesting premise, and I love the overall look-and-feel of the game. It's really quite a lonely place, and the low-fi look adds to that, but everything still makes visual sense.
I was initially a bit lost, but once I found the toolbox, it was clear what I had to do to progress. I was able to escape on my second attempt. (Well... at least I didn't have to join the Army.)
Thanks for including a Linux build!
