Along with a programmer to code the game i think you will also require a designer to design the lay out of the levels. Your panda and Demons are cute and engaging, but users will only commit to a $0.99 purchase if the game play is fun and interesting .
I have a proven track record designing for PC, Mobile and console games, including The Sims and FIFA for EA, as well as several Wonderbook titles for SONY. I have over 12 years of experience designing intuitive and fun games. This includes everything from flow and game mechanics to meta game systems and of course missions, levels and scenarios for multi-million AAA selling game.
Of the 4 Iphone/ipad games I have designed in the last year 3 have reached the top 20( including a number one.)
