One of the best jam entries I played ever. It could be a paid game if it wasn't as short.
(spoilers incoming)
Only drawback is that the puzzles were not super intuitive. The QR code was too small to scan, I had to try several times, I started to think that it was fake. And the command lines error messages should have been "permission denied" and "unknown user" or somethething like that, so the player could understand that they were in the right track.
The end was a bit unsettling. Or maybe I missed an alternative ending and just got the bad one.
