Yeah it's unfortunate, you can give the downloadable version a play though, it is identical to what the HTML would have been. After the voting finishes I'll fix the HTML version, I'm sure I already know how to do it.
Seems like the same issue I had before I got around the 90% load-freeze, Simply put; don't compress the build (in player settings). It seems right now it's Brotli compressed? Atleast that's what the console tells me. It should be none, then it should work.
