That with its pixel art is styled so beautifully and so hard to read at the same time. Couldn't read it at all. (It's not an eye vision problem, reading pixel fonts just is quite taxing on the brain).
I found it hard too. Perhaps the difference with the other people responding is the size the font is rendered. On my screen, the distance between the top of a "d" and the bottom of a "y" in the body text is 7mm. That corresponds to font size 18 in Word, or 22px in the browser, so basically a chapter heading.
