The difference between Dungeon Hunter - Free and the paid Dungeon Hunter games?

[chismizmak]

I was just reading the reviews on the games Dungeon Hunter free and the paid Dungeon Hunter in the app store for iPhone, and they have averaged 4 stars each in rating. I am wondering what's the difference between the free and the paid other than one you have to pay for. Is the free version limited, less game options, less mission, less rewards/treasures, incomplete campaign or has a time limit? Also if I get the free version and decided to get the paid version later, will my save game stay or will they be gone? Any feedback would be appriciated.
