I can only access stupid ODUS!!! I get a message on the day screen that says "Soon there will be new places to explore. Until then you can replay previous levels to gain higher scores and more stars. " WHAT? How do I get back to by 500's ??
It sounds to me like you don't have the latest version of the game as this is what normally appears at the end of an update. Have you checked out your app store to make sure there are no updates available. Check this and let me know
