It will be good idea to have coffee trees that we can harvest with collectors who pick the coffee beans from trees and a deposit boost in the
provisions house to restore it (fertilizer)
and we can use coffee beans collected to buy items just like magic beans but the coffee is available for all levels
and also a building that make coffee drinks with water and beans and we use that to hire new kind of elite troops
just an idea ......hope to see it in the game soon
