Make free and paid versions of a game (iOS)

So, I built a game called 3Dash and published it on the iOS App Store for free, but then, I made another “version” that I planned to sell on the App Store that had much more content and many more features. I tried to publish it, but then I got rejected by Apple due to: "Guideline 4.3 - Design

This app duplicates the content and functionality of other apps submitted by you or another developer to the App Store, which is considered a form of spam.

Apps that simply duplicate content or functionality create clutter, diminish the overall experience for the end user, and reduce the ability of developers to market their apps."

Can anyone help me get around this and publish my game? Any help will be accepted!
