Maybe it's easy for kids to read, but I found the font too bold and the letters too close-together to read comfortably. I gave up before I could read all their justifications for those decisions.
But that might've also been the weird scrolling behavior of the page that ruined it for me.
The CSS has
{ letter-spacing: -.04rem; }
It's across the entire site - no exclusion for this page (or for their .kermit-font class). So it appears they've missed the fact that they're altering the look-and-feel of the very font they're presenting in this post.
I assume that's to work around the high width of the font. Information density seems too low for paragraphs of text with that width.
I could see this current version (without the spacing hack) being the "easy-reader" version, and then make a "YA reader" variant that's lower weight and horizontallu narrower.
But that might've also been the weird scrolling behavior of the page that ruined it for me.
