On the surface I like the game however there are many problems. For starters after the last update the game won't open. It crashes randomly and the biggest one for me was after an event where I earned all but the last 2 rewards the game crashed after a boss challenge (not unusual) but then when I logged back in it had deleted all of the rewards I got from the event. I sent an email about it to the developer but I haven't heard anything back. In game currency is hard to earn and very expensive.
