I liked one idea if you add option to add people to the farm that might be set the farm to lively environment. Right now I can see that only animals can be added to the farm. Also the people must do some activity by themselves that should be appealing to our eyes. Just think a farm without peoples is boring and farm looks static. One of the option is in a way that add people to farm by purchasing with coins. Second option is add more and more visitors as level increases. If the option adding people is by coins, don't set big amount of cash to buy people, make it less pricey so everyone can buy as they want. Its' up to you but please add some people so that farm becomes lively instead of a dead state. Also, remember that all types of people can be bought like kids, adult, male, female, boy, girl and each one should have different types of caricature and behaviors. Thank You.
