Content of the article itself aside, I think this is a very well designed piece of online content. Very easy to follow and way better than some wall of text article you'd expect to see!
For me, I'd much rather read the "wall of text". I found myself wanting more depth and detail about the story.
I too enjoyed the nice storytelling and graphics. And knowing it's only about 10 pages helped to start following it. But being used to more information I felt like "Is that it" in the end. Could work better with linked in-depth article in the end.
I find the side scrolling and paging annoying. I'd rather just have all the content on one page. Just let me scroll vertically like a normal webpage.
