I have been playing this game since it first came out on iOS and have purchased all of the additional content for my iPhone. When we switched to Android phones, I had to start over but wasn't able to verify my prior purchases / accout. This game is good enough, I'm happy to buy the full version again, but the online requirement to validate a purchase already made in order to play the additional content has always baffled me. This game isn't complex enough to warrant any online requirement.
