Yeah sorry WebGL version just won't work for me.
You'll have to download the game to try it.
I know what's up, I was having the same issue on day 1! It's because your project uses Brotli compression. If you go to build settings, select WebGL and look at the configuration, somewhere it should let you go to player settings. If you open the publishing settings from the dropdown, change the compression from brotli to gzip (or no compression also doesn't break) and build. It should then run in browser :)
