Everything in this game takes too long. Hatching eggs, breeding, waiting for buildings to upgrade, ect. Food requirements for level up after level 20 are obsurd. Game has too many popups asking you to spend money whenever you open it. Drains my phone batter super fast; no other game I have does this. A lot of the dragons look boring or dumb. Habitats are too expensive. Combat super lame, like a bad Pokemon rip off. 2 stars because despite everything, it's managed to hold my interest.
