This is a fun concept for a game, and I appreciated the style of the story.
I did, unfortunately, run into some trouble with how the game was structured. Is there a way to not make the third zone available until I can actually go to it? It was a little offputting to see that as an option, only to be told I couldn't go there.
I also wasn't always sure what had happened when I did (or tried to do) something. e.g. the door code, which I assume I got wrong, but "Beeeep" and refreshing the first screen didn't really make that clear. Did I die?
