Here’s a quick test of a Unity Web project. GitHub Pages doesn’t seem to support Content-Encoding, so I can only build uncompressed for now. That means it’s an 80MB load instead of 6MB (Brotli). You might want to flip the ringer switch on the side of your phone to hear the audio.
But this is pretty cool! I’ll make a half-decent level next. Let me know if you have any issues or know how I can get Brotli compression to work here.
