No, You didn't die. The concept was, that nobody should die in the game. Thank you for trying it.

I haven't found the reason, why are you couldn't reach the third zone... The game was maybe a bit buggy here and there (the 4 hours weren't enough to serious playtests), but the main story can be reconstruated. When you complete the first two zones, their links should disappear but the third link was stable, at least i thought so... i'll check it...

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?
