I loved playing this game. It felt very atmospheric and I could feel my blood start pumping when I entered a "danger" state while far away from a safety zone. Some sort of visual cue on the doors would have been helpful as it took me a while to realize that only certain survivors could open certain doors. I also would have loved to see each character have an ability or benefit beyond opening specific doors.
All in all, I really enjoyed this submission and think the atmosphere was hands down the best in any of the jam games I've played so far. Awesome job!
