I updated my submission too with a Linux build, but I have no idea if it works... HTML didn’t work for my game, I tried a few different methods.
have you renamed the html file to index.html ? also which browser? firefox seems to work best
I did. I tried zipping the file in different ways too, but no luck. I have not tried Firefox, but tried Chrome, Safari on iPhone and Edge.
chrome is known for not working correctly, try firefox
