Recall - Game center, ads, UI (repost)

his project is to add some functionality to an existing app and to enhance the UX / UI. It has to work on iPhone and ipad as it currently does. As discussed, the following items are part of the project. - need to apply better UX - ad and in app purchase to remove ad - Game Center - leaderboards (view, post scores), and the ability to play multiplayer games - Changing from arrays used in the code to use an SQLite database instead. It'll have to be encrypted (maybe use SQLCipher) There should be a different leaderboard for each difficulty, one for easy, one for medium, one for hard. Multiplayer games will be against a random opponent or against a friend who is on the user's friends list on Game Center. The user can choose whether they'd like to play against a random user or against a friend. The person starting the game will have the option to choose the difficulty. Since the file is too large it is on DropBox.
