This was quite cool! I was a bit confused by some of the rules at first (like the fact that you have to put the sawmill on a forest tile), and I felt like the UI could have shown more info by default without having to click into the menus (such as: the number of buildings you can currently afford, the number of tiles you can currently buy, price of tiles when you hover over them, etc). Anyways I liked it though and I thought the research system and building synergies were fun. My score was 5450 (proof)!
