The main gameplay loop is fun, satisfying. It doesn't provide any challenge though, when you build a whole lot of gold mines, trees and taverns, and then a whole lot of archer towers and upgrade them. With proper balance, with more scarce resources or limited amounts of buildings, I think it would be very fun.
Third person view was cool, but I really only used it to look at where enemies were coming from. I punched them in the beginning, but it didn't seem that useful. It would be cool if I could repair buildings in that mode.
