Im not even able to finish the first set of quests without spending real money to build barracks or a marble hut because to go any further in the game you need more diamonds then they give you also you need diamonds to upgrade your buildings after so many times of upgrading due to needing to do research. There should be an alotment of diamonds given out each month or at least some way to win free ones by doing tasks. Also i cant even find how to participate in events this needs to be explained.
