I have never gotten a single report similar to that, from 0.23 or 24, so somehow it's unique to you. Might have something to do with the browser or OS? idk.
The game won't go anywhere on 8.0, it's just a backend engine change. Will cause some weird bugs and errors for a few days as I and beta testers try to find and fix them all, then 8.0 generally has better compatibility and features than 7.5 did. At least with modern stuff, idk about older OS.
8.0 didn't have web support at all for a long time, re-adding it was very recent. I'm not sure how well it works yet. Itch and renpy both have a variety of issues with web versions unfortunately; there's missing functionality and major issues on itch's end as well as what seem to be effectively unfixable problems on renpy's end for a web game as complicated as this.
It's possible I will be able to find a workable middle ground down the road, but right now I can't make any promises about web version anytime soon.
