I'd be happy to try it out in Kindle, to combat focus problems. Open dyslexia was somehow helping for some time, but I reverted it back eventually.

It feels like poor taste to force smooth scrolling on a page that is intended probably to be read by a target audience who is more likely to use assistive technologies than not.

I fail to see why would the arguments be only valid for kids

Is there any information on the licensing of this?

It's going to be included with MSWord, sure, but what if I want to use it as a webfont?

Hmm, it looks like someone took comic sans and tried to make it more like arial. My first thought was that they made a boring version of comic sans.

Dont they already have comic sans? also nice timing over easter to stimulate the normies and thier kids.

Looks like a much more pleasant alternative to something like comic sans. Friendly without being completely unserious.

nice extra features, though the speech' subtitles has all the words jumping up and down - wouldn't that make it harder to read?

Nit Picks:

Underlines with letters that go down (g, y, j, p, q ) don't keep the underline continuous.

Kerning on the emdash (—) is a little too tight

This might be a good successor to comic sans. Readable but still fun to look at.
