Good game, but not all bridge designs will work Yoy. Take the design of the Golden Gate bridge. This game will not support that because you need to support your bridges from the BOTTOM.
Fertility of the pastures determines how well your soy fields will grow and your cows will grow. Or something like that. I know you have to move them if fertility gets too low.
Just because it doesn't have achievments doesn't mean you should rate it lower. Kongregate adds badges, not the developer. Rating it lower based on absence of badges means the developer will not have as good chances to earn money to make more games.
