Mobile development

I need an Android and Apple app. I would like it designed and built. I need a game app, the avatar is a customizable character which can be changed into different characters using points to spend which are earned through playing the game or online purchases, the game is to hold on the screen for the character to fly up and to let go of the screen for the character to begin to fall back down, the user is meant to allow the character to pass through gaps and avoid obstacles and to aquire power ups to improve their points, different backgrounds can also be acquired through points
