Unity will output to iOS, OS X, Android, Windows Phone 8, Windows 8, Blackberry 10, and many other platforms. Organization of your code and project is paramount; otherwise things will get very messy very quickly. Why don't you try making this game work on some other platforms? The best way to learn is through experimenting and performing, so what are you waiting for? If you do get stuck, the forums at http://forum.unity3d.com are really helpful. Hopefully you feel comfortable with the basics of programming on Unity for Ouya now and I look forward to see all the cool new things you come up with. This demo alone could be expanded to have hundreds of levels, more sounds, and some better graphical effects.

My Twitter username is @Gary_BBGames and I'm happy to answer any questions or help out in any way possible if you get stuck. If you create any apps or games, do let me know and I'll help promote them for you.

Thank you for taking the time to go through this book and remember, it's all new territory again and anything can be a success!
