Playing Jetpack Joyride, I believe I know how to Halfbrick development process works. The first step is to come up with an impressively ridiculous idea, like a ninja slice of fruit, or double-stick shooter with a Zombie T - Rex, or in this case, the game has a machine gun jetpack. The second step is to go out of ideas, and maximize exception. Jetpack Joyride follow this brilliant formula for T.
