Howdy, friends~
I think the source of the issue is that there is a large discrepancy in the kerning in the woff and woff2 versions of the font as opposed to the kerning of the otf version in the current release. otf more closely resembles that of opendyslexic 2, but the woff versions are kerned much wider. some anecdotal feedback is that the spacing between words is so wide that it can create distracting vertical "snakes" for some readers.
