There's certainly a large amount of anecdotal evidence that a decent percentage of dyslexic people benefit from using Comic Sans. I don't know if there has ever been a formal study though.
There's also a view that all dyslexia doesn't have a single cause. If that is true, then there may be different things that are helpful depending on the exact cause.
Comic Sans is a great font.
Kermit seems like an impressively shoddy imitation in my opinion.
Eldrich horrors like Comic sans may be discovered, but never created.
Kermit Sans is like an artist's imagining of Cthulhu gleaned from the rantings of a person driven insane from glimpsing its Eldrich form.
As a neurotypical, Kermit Sans looks like it has the soul and intention of Comic Sans, but with the jankiness smoothed out. I quite like it.
