I'm guessing no, as the game is in a basically finished state and it's unlikely you'll go back and add new features. Still, you never know if you don't ask! My original save game is on my son's iPad and he'd be really upset if he loaded up the game on mine and the save was different. (He's only four.) So I have to only play it when he's not using his iPad! And it would be nice if the save was backed up to the cloud, too.
