I really like the overall premise. Taking something as normally peaceful as farming and putting it into a post-apocalyptic setting gives the game a pretty interesting atmosphere.
The idea of having to keep everyone alive while protecting what is basically the last bit of life left in the world is a nice hook, and I think the atmosphere is probably the strongest part of the game for me.
I would like to see a little more feedback and clarity around what I should prioritize, especially early on, but the core idea is definitely interesting. With some more polish and content, I think this could become a pretty unique farming/survival game
