Great game! I felt like the balancing act between putting out fires, gathering additional resources and maintaining places to put down new settlements was a great gameplay loop. The art, music and sound effects were all very polished and the game scope felt excellent.
I will say, the beginning of the game was a bit confusing, because there wasn't much guidance about how to place building and what they cost, but the card format used was intuitive enough that I figured it out without too much trouble.
I also wish the end condition had more to do with the player's input. I think it would add to the strategy if you were trying to accomplish an ultimate end goal, like maximizing survivors by avoiding building in a predetermined lava flow or (inversely) maximizing the ultimate damage via your placement of buildings. I think this would help the strategy part of the game go one level deeper.
Regardless, I had a lot of fun in my run, and I really appreciate the time you took to put such a neat game together. Thanks for making it!
