I really liked this game until they did a major update changing the cost of some purchases in the game. I was at the max level with most of the dragons and around a total of 16 parks, 5 egg spots, and somewhere around 380 dragons including all the major ones.. The update totally reset my park back to the beginning. Now for a second time I have lost all my progress because of the update on or around Feb. 14. The app became totally inoperable. I honestly think DECA does it to people that don't buy
