Ooverpopulation! can't place anything
I would suggest making the building placement more clear. On the edges of the map, it's not clear whether or not you can place a building. Furthermore, the collision of castles is a little deceptive (maybe an invisible grid would help)
Really fun project! Would be thrilled to see it expanded a little :D I like the concept, the dynamic between crime and happiness/econ (markets are definitely OP hehe). The random events help spice the experience. Nice work for a game jam. Impressive!
