Nicely designed. I like how the panels scroll independent of the background. The buttons are nicely designed too.

Have you thought of making the background image more faded or more subtle? At times it's a little distracting from the main story panels. The chapter title also needs to stand out a bit more from the background. It's difficult to see since it is plain text. Just my thoughts. Also, at the bottom of the story on the first page, the "next" button is not working. Is there anymore to this story or is that one of the non-working links you mentioned?

I know what you mean about checking every link...headache!
