Chapter 1
1 See en.wikipedia.org/wiki/Manic_Miner to learn more about the game’s history or search for “Maniac Miner” on YouTube to watch the game in action.
2 For example, if the zombies kill you in Zombieville USA, that’s it—you’re done. You have to start over again at the very beginning. However, version 1.4 of the game released for the iPhone 3.0 SDK gives you the option of adding lives before you set out to save the town from the swarm of zombies. For more info on Zombieville USA, search for it on the iTunes App Store.
Chapter 2
1 Books available for OpenGL include OpenGL Programming Guide, OpenGL Shading Language, and OpenGL ES 2.0 Programming Guide.
2 Checking out game development forums, such as www.idevgames.com and www.gamasutra.com, is a good place to start looking for freelance graphical artists to help with your project.
3 Zwoptex (http://zwoptexapp.com/flashversion/) is a flash-based sprite sheet generation tool that allows you to perform complex arrangements of different sized images. A cocoa based version can be found at (http://www.zwoptexapp.com/).
4 You can find Parachute Panic in the App Store by searching for Parachute Panic.
5 Neon Tango (www.freeverse.com/games/game/?id=7015) by Freeverse is a great example of what can be done with simple geometric shapes. It helps that they have executed the game with extreme precision and some dazzling effects, but you get the idea.
6 Hiero can be found at slick.cokeandcode.com/demos/hiero.jnlp. This link will run the application over the Internet rather than download it.

5 Vertical synchronization, or vsync, refers to the synchronization of frame changes with the vertical blank interval of the screen.
6 In Objective-C, methods are referred to as selectors.
