On the one hand, I dislike the multiple layers of abstraction removing the programmer from the metal and killing performance. On the other hand, being able to hack the source code like this reminds me of my childhood Apple IIe, cracking and hacking days. Adding extra lives and other cheats was THE reason I learned how to program. If I grew up with today's binary apps and need for developer kits, I'd likely spend more time consuming and less time hacking.
