Neat concept! I happen to enjoy point-and-click survival games... I've dabbled in this format for a jam in the past and it's a really nice way to efficiently lay out a larger world for the player to engage with. Some added sounds and ambience would really elevate the experience!
Neat touch having the only people you encounter be reduced to black, faded, husks. I think the gameplay would work in service of the themes of surviving in a war-torn city with more of a sense of peril. There didn't appear to be a fail state or consequences for letting the stats bottom out, which felt kind of unfortunate. It also didn't really feel like time progressed as I traveled around the city and did things.
It just feels like there are some important pieces missing, and while it still gets some good ideas across, I'd love to see what this game would look like in a more complete state!
