Write an iPhone application

I've started a game for the iphone 5. I'm using the gamesalad program to build the game. Majority of the game is complete. I need someone to add the last functional components to the game in order for it to be user ready on all levels. Examples: Pause & un-pause Game over (all actors & spawns to stop) music stoping when game is over. Reset button Recording high scores The game is a continuous gravity game, similar to flappy bird. With a bit more components & features . I would like to be part of the process in completing the game. I'm using Mac.
