The point of this game is to hatch your eggs. In order to do so, you need pearls, and LOTS of them. Since they give them out with a stinginess that would make Ebenezer Schrooge shudder, I assume that they count on you getting desperate enough to buy them. I say desperate because they wont stop harassing you to either pay to hatch your eggs, or dump them to free up space. How the hell is that relaxing???
