I'm new to game at the moment, but I am very impressed and I enjoy the game at a free to play level so far to the point that I felt inclined to make item shop purchases just out of gratitude and deals. Graphics are good and the gameplay is fun, but ever since version 3.7.0 the app doesn't allow me to play the game while using external storage for the data. If i try to open the app it instantly crashes which is a major problem for me since now i relying soley on my internal storage to play.
