This is a gem! I really enjoyed playing this. Played like 7 rounds until I was finally able to survive long enough to build the bunker. There is almost nothing negative about it. Well the ruins thing was not quite clear for me: If you send 10 people out, do they all go for the ruins and risk dying? I avoided those, so I never found out, lol.
Great atmosphere, nice choices on mechanics and balancing. Super well done!
