Spent quite some time on it, as many as said the amount of content is indeed insane!
I think perhaps focusing a bit more on improving the UI (as you already noted) would have gone a long way in improving the feel of the game! Stuff like price of the buildings is hidden, and it's not clear why wood gives you money but wheat doesn't. Better in-game description would have helped a lot!
Regardless, amazing effort and amazing game. Could easily be expanded in a small city builder, as there are never enough of those!
