Really liked this! The art style was awesome and the audio was nicely done (although I'm not sure about including the Wilhelm scream lol). It took me a few tries but I did eventually get a bunker built - maybe the RNG is a little too hard at the beginning of the game but maybe that's part of the fun.
Also I'm not sure but I think the ruins may be bugged, it didn't seem to do anything the first few times I clicked and I wasn't sure if I was getting something from it or losing humans. I also was a bit confused by the shelters as they said they lasted 3 days, but they seemed to last forever?
Overall though a really great experience!
