Me and my friend (Toh, another illustrator) created a IOS game (for iPhone & iPod) called JUMPEEJUMP already approved by iTunes and ready to sale today!
It told us more then 2 months to complete it from idea > sketch > fight(for better game-play) > script > art > modify > fight(agains) > modify(agains) > submit to iTunes > Ready to sale.
Please visit our JUMPEEJUMP website for more info on the game and do feel free to give us some comments.
