Really enjoyed this! Adding a nice big image of the finished city at the end was a nice touch. I'd love it if you expanded this with different districts/buildings giving bonuses to adjacent tiles, like schools and parks adding bonuses to houses.
nice idea! Originally when building this game I also wanted certain tiles must be next to each other along with the "disallowed adjacency" but I'm worried it might be too complicated for the players. But having it optional could be good way to do this.
