Firstly, this is frikking hilarious. I giggled so loudly while reading it that my girlfriend asked what I was laughing at and she was so captivated by it that I had to sit on the couch with her reading it, flicking to the next page of the downloadable whenever she'd finished.

Secondly, I applaud the style/premise of the book. Cats especially are aiming at an underserved demographic that would absolutely be interested in programming but do not have the same number of and level of quality of 'ins' (ways of getting into programming) as other demographics. Along the same lines I would love to see 'scripting for Sims 4 builders' or 'Love Calculator and other scriots for your next sleepover'.

Thirdly, I really like the way that this is pitched. I feel like so few tutorials give a high level overview of programming rather than diving into specifics of languages. I can only think of "Hello Ruby" as being analogous, although I'm sure others exist.

Finally, I love the art style. Not much more to be said than that.

I can't really think of anything critical to add.
