Very fun game. Played it for a couple days and the mechanics are simple but the depth is relatively high, which is great.
It might be worth mentioning rules about the tile generation somewhere in the rules but maybe that's unnecessarily specific (ex: tiles will never have more than 1 windmill, tiles will never have more than 2 grass areas, the game will always generate 12 windmills and maps always have 8 hills so you have 4 windmills you can place elsewhere without losing points, etc...).
Getting 125 feels like it's partially rng but I guess that's not necessarily a bad thing. You can try to maximize your chances by leaving your remaining grass tiles in the same "zone" but ultimately whether or not you can connect them is dependent on what your last few tiles are. Also going for 125 is definitely different than just trying to consistently hit 120 but again that's not necessarily a bad thing.
Going to quit now before I burn even more time on this.
