The text is too small and spans most of the screen. Difficult to read on big monitors. Reading that grey block on mobile is also really straining. I actually just gave up and came to read the comments instead.

The word 'download' is exactly the same font as everything else. So it's hard to find. Why not have a button that stands out? There are 2 links called 'click here'. So you have the read the surrounding text before knowing where you want to click. I can't think of a good reason not to have a clear call to action button that stands out from the rest of the page.

Compared to almost any modern site, this is really bad.
