Unsatisfactory. Non paying players are forced to miss out on completion of events and challenges because their energy of which we only get 30, can get used up in a space of less than a minute and yet we wait hours for our energy to regenerate. It's extremely frustrating as I am a huge Harry Potter fan, but this game just frustrates me because I am unable to complete half the events. I'm a student and don't earn a big income so I cannot pay for the game and I wish the creators had thought of that
