Couple points of feedback:
1) Cottage upgrade cost grows exponentially out of control. I upgraded my first cottage and then never had the resources to ever upgrade again, and waiting on enough resources to build additional cottages was the defining experience in late game.
2) Building placement doesn't seem to matter, so why restrict placement to being right next to an existing building? Makes a compact looking city but also makes it hard to find buildings sometimes.
3) Military is strong and doesn't require actually engaging with getting strength growth to handle everything in the game quite easily with 1 barracks.
4) Ability to delete buildings would be nice. Especially due to aforementioned food being a limiting factor in late game.
