Fun and exciting to play. Creative. Events come one right after another event ends. BUT...requires WAY TOO MUCH ENERGY to accomplish a task or to just make something the event requires, which by the way makes it FRUSTRATING to play!!!!! I reached level 19 because I made purchases just to have energy to complete a task. Even upgrading buildings are hard. Oh, it requires too much things which also requires more space...so needs to upgrade storage from time to time, which is also difficult.
