Design my Gaming App from scratch!

The object of the game is to collect food and other rewards while running through an endless game world through the thick grass. Rocks, water, and bug animals; such as snakes, frogs, etc and other obstacles must be avoided by performing well-timed jumps (swipe up), into ant holes (swipe down) and sideways moves (swipe left and right). Occasionally the characters jump, and swim over rocks and lake. Special missions reward players with bonuses for accomplishing specific tasks. The game ends when the the character being attacked (surprisingly scary) stumbles and is apprehended or crashes directly into various obstacles. This is a horizontal played game that has many in store purchases. I need a loyal and continuous game developer who will help develop this game and be in contact with the future for updates and questions.
