Hi, I'm Ofihombre, a developer and user using the itch.io app for download & play HTML5 games (specially unity webGL games), because lately none of the installed browsers allow me to play almost none of the downloaded games (just barely Pico-8).

And this is where entry the itch app entry. Is a very useful application to be able to play most of the HTML5 games downloaded so asn't to depend too much on the browser. Almost all Unity WebGL games worked very good for me, even the most recent ones.
However, as of version 25.4.1, things changed for the worse, now almost all webGL games don't start correctly (specially the most recents),  and got stuck with the loading bar almost full for minutes, hours or even days to start the games (literally are already unplayable).

And I could say the same of other cases as in Bob the Brawler who got stuck with the purple screen, and now thanks to version 25.4.1 I can finally play because it was already fixed. Why isn't the same with Unity WebGl games? I don't understand.
