This is fun to watch! I included it in my ProcJam compilation video series, if you’d like to take a look. :)

Watching the town grow is fun.  Are houses required to be adjacent to the farms that feed them?

I made a generator that's pretty similar: satisfying supply & demand, packing rectangular objects on a 2D grid, and even the orbiting camera. I'm inspired to make some improvements after seeing your generator.  https://cliffordius.itch.io/spaceship-wrecker

Very cool idea, would be fascinating to watch with a lot of different needs, kinda like a reverse Sim City
