If the levels/code are passed in plaintext and simply parsed by the app, it is hard to argue it is different or less secure than sending photos in Instagram or playing a game of chess. What is passed may be parsed by the app but it is contained and limited by the boundaries of the app. The app store is much more concerned with stuff like apps that update themselves to install payloads or change the approved app on a fundamental level.
