if i start game it say = build compression was enabled but web server hosting the content was misconfigured to not serve the file with HTTP Response Header "Content-Encoding: br" present. Check browser Console and Devtools Network tab to debug.

What can i do

you need to go in your project player settings compression none

Go to Edit > Project Settings > Player > Compression Format (open Publishing Settings to see it) — set to Disabled

By default Compression Format is Gzip, and this is making this error (Itch io can't launch game with this type of compression)

i do it 5 minits before deadline

i am happy beacouse my project is small so build is fast
