Bought it, went through 1/2 of it in a day, think it is really good. Informative watching the author's design choices and refactoring of the code base as he added new features and builds up the game from "hello world" to pretty full featured. I am a professional programmer and in my opinion this would be tough to understand for someone who wasn't already an experienced programmer, but I've never used Lua or coded games before.
