About the Author

Michelle M. Fernandez is a mobile game developer and cofounder of MobiDojo (http://www.mobidojo.com). She is also a mentor to aspiring artists and programmers trying to break into the game industry. After experimenting with several game engines over the years, she was introduced to Corona SDK in late 2010 and has been an avid user of the program ever since. She enjoys creating tutorials and new game frameworks for others to learn from. When Michelle is not developing games, she is spending time with friends and family, playing video games, traveling, and constantly learning new design paradigms.

I would first and foremost like to thank my family and friends for their love and encouragement throughout the production of this book. I'd like to thank David Roper for his support and patience during this project and for always pushing me to do my best and succeed. I'd also like to thank April Quileza and Yanglyn Ou who have always been there for me to help review my work and who become my personal cheerleaders when things get hectic. My greatest appreciation goes out to Carlos Icaza, who has been a wonderful mentor and a great friend. I would like to acknowledge Walter Luh for continuing to give Corona developers an amazing platform to work with. A big thanks to all of the Packt staff for giving me this opportunity to share my love and knowledge of mobile game development through this book.
