This was a wonderfully inventive idea, with some great writing and a cool mechanic. I managed to survive until all my peers were dead. I loved the presentation and I loved the writing in the cards.
My one piece of feedback, if you were to take this anywhere, would be to have some kind of change to the cards you get depending on your stats, as this would make it feel like you're moving forward in time.
But yeah, brilliantly dark and fun idea, and I had a lot of fun playing it. Great work!
