Thank you so much for playing and for taking the time to leave such detailed feedback!
It's really encouraging to hear that you enjoyed the writing and the hidden details in the OS, as I had a lot of fun making them.
You're completely right about the lack of instructions—I ran out of time during the jam to add a proper tutorial, but fixing that is my top priority if I continue developing the game.
I also love your idea of adding web searches or hints to make email verification feel more like a real detective mechanic, and clarifying the survival loop with actual win conditions is definitely on my list. =)
