the demo version isn't really good for learning becuase it is only 30 days, granted it is helpful, but to get more experienced you will need months/years to get excellent at it,
Im the book, i am on page 200+ and so far there has only been one game tutorial, and that was a text game with only about 20+ lines of coding. The book starts from the basics and has lots of examples on everything you need to know.
So far i am on chapter 7 'data sequences and arrays' and so far it is very confusing, but ive only started the chapter. everything else in the book has been very helpful to me so far.
so good luck, and enjoy your 700+ page book. =D
