I love the concept of recieving 2000 gems. It is a great way to appeal to the player/User of the game. Some of the issues I acquire are some of my buildings are lvl 0. The app constantly crashes during gameplay or typing. Upgrading a building with a "error" poping up usually after a few tries trying to upgrade it,It was upgraded to lvl 0. The lag is almost usual,I'd suggest giving out more resources during the first start off of the game/City because we are trying to get everything bult and building takes resources. Other problems I deal with are not being able to deconstruct some of my buildings. I'll update my feed back further more
