finally. web version works https://godotengine.org/article/godot-3-3-has-arrived#html5

I can peacefully sleep.

WHOAH now Godot 3.3 fixes HTML5 loading!!!

IT NOW WORKS!!!

Go try load this file in this game page here! follow the step and voila! Loading Bar working!

thancc Fabio, and more Godot contributors!

we also have updated the documents too!

and btw

if you downloaded the HTML5 version and `failed to fetch`,

your browser is afraid of loading stuff from `file://`. you can do either:

• run mini server running that index.html
• force browser to allow loading other stuff from `file://`

so yeah basically, you need to host the HTML5 version, you can localhost it too, to make the gameplay experience looks like you're loading things from `http://` or `https://` like browser error says.

if you are too lazy, then maybe stick running this here, this should work on every browser hopefully. sorry for inconveniences. some browsers becomes more fearful these days, but that's the security measure.
