UI Update/Bug Fix (iOS)

I have an existing trivia app that needs a bit of UI touch up and few minor upgrades based on user feedback. User Feedback: * App crashes after level 5, possibly due to In App Purchase problem. * Music in the final level over laps video after beating final level. Music needs to stop once player beats the game and end video is started. * Add scoring system & game center compatibility. UI Changes: ****Note: I have already created all the new art, you just need to put everything in the right place.*** * Home Screen: Update home screen with new layout. * Change countdown timer: Currently the timer is number based. I need it to be a graphic based time where the bar gets shorter as the time counts down. * Timer settings: Instead of 20 seconds as default player will now have only 10 seconds to answer the question. * Number of questions per level: currently there are 5 questions per level there will now be 40. * Make art iPhone 5 compatible. (backgrounds & menus stretched to fit 4" screen is ready) * Ad RevMob ad system to the game. * Pop up message after level 1: "Love this game? Hate Ads? Get more power-ups, unlock 70 levels, and get rid of all ads now!" * In App Purchase: Currently, the IAP is set to unlock all levels once the player purchases the game. * The new version will 1.) Unlock all remaining levels 2.) get ( 5 ) 50/50 chance bonuses per level. 3.) Get 5 stopwatch bonus per level. 4.) Remove all Ads * Add custom font for game interface.
