After palyed for over 160h, I really like this game. So that, I have some idea about wall, gate and bulidings. First, I hope in the future versions of the game, the thin walls could be automatically upgraded to thick walls when I built multi-layer wall. Second, I think, if the wall gate could be more complex or bigger the wall building will be more gamepaly. At last, Could you add some landmark building such as church.
