I got now a score of 18. I'll come for you all. Watch out!!!! and as a side note: Sometimes I get logged in into Gamecenter, sometimes not. I really have not found out what's the reason. Also, on my iPhone 4s (with ios 8.4) I have a problem with the cross promo ad. It just makes the screen darker and I can hear the sound, but there is no image from the ad. I have to tap the screen and this takes me automatically to the appstore, canceling brings me back then. I suppose this has rather to do with the old ios or the old aspect ratio of the phone, so not sure if it is important to fix. It happens as well with the latest update.
