The game itself is fun. The problem is that every time you open a chest, click your reward or try to upgrade something there is a high chance the game freezes. It happens on two of my devices and to a friend who also plays. I also purchased a 5 dollar pass and it did not add the pass to my game. I reached out to support and I am waiting for a response. May update depending on their response time and actions. Game is super fun, but until the issues are worked out 2/5 is all I can give
