What can I say, town building sims are my jam! And this is quite the visually pleasing one too boot!
I think the main thing is how easy it is to get softlocked. In one of my playthroughs the mine seemed to need more people to work there, so i can get more coal however I ran out of coal to build a house to get another person, so was just sorta stuck (atleast that's how I understand it). In games like banished you can directly dictate where the villagers are working and what one, so if you ran out of people to work the mines you can just take a bunch of builder to go do that, perhaps a system like that is worth looking into?
Nonetheless this was great fun, good job!
