I had a lot of trouble understanding how the game worked, I was trying to click the trees and the farm to add workers to them, until I realized I should be clicking on the sidebar. After I understood what was going on I felt it was really easy, I always had plenty of cure stocked up with very few pops working on it.
That said, it felt really good to see them numbers growing, and I really liked the simplicity of the rules. The UI, although a bit buggy, was very satisfying to use.
