I always do love seeing people mimic operating systems inside of games, but yeah this was sweet little horror story, on my first run I feel it was left bit ambiguous about the story, but I personally enjoy those types stories >:)
I also encountered the same bug as Dotoloto, and to be honest, I really liked it; as in, major creeps when I didn't even open the email application and being basically jumpscared by Enox downloading. Sad that it seemed to be a bug, but worth thinking about for the possible future development! Regardless, very nice short story, good work!
