Hmm... I deleted and reinstalled this morning, now the game works fine. Lost my progress again, but considering it was my 5th playthrough, that's no big deal. Just glad I can still play this... =oD **apparently, I downloaded the old version because it's telling me I need to update again... Guess I'm lucky. No updating for me. =o/
Now it crashes on the opening cut scene on iPad 3 (iOS 9.2 no jailbreak). On iPhone 5S (iOS 9.2 no jailbreak) it works fine.
It works great on my iPad Air and iPhone 6+. I can see that the developer is working on a fix for those that have issues still. For me, it's absolutely great to play this amazing game again, and fantastic with 20 new levels. ##
I tried playing this on an iPod 5G and it did nothing but crash at the title screen. It seems to work fine on my iPhone 6 tho. I don't have GameCenter on my iPhone tho, so not sure if it's a GC issue or what.
This is temporarily on sale at a discounted price. Although there have been no updates for a long time, it does not seem to be a problem with the progress of this game until now.
