Sorry for leaving this mod in such an odd state! I was playing around with modding back then, and then forgot about it.
But I've just come back to it, and made an overhaul! There's now a little story that guides you through the first steps. There's not much content yet, but you can get an idea of where this will be going.
My plan is to further improve the city generation, add supply chains, and a bit of story along the way.
I'm not sure how an increasing population should help the player. What do you think about an increase in productivity if the citizens are happy?
