The game seems to get stuck on the loading screen. The red box at the top actually has some text in it, but it's offscreen. I've copied it below:
Unable to parse Build/UP v1.2 - WebGL Build.framework.js.br! This can happen if 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.
