This does not work at all on Android Chrome. The about dialog flies in super slowly, continually re-layouting the text, and there's no "small cube" and no way to dismiss the about dialog either.
The background looks tantalising but maybe a little more testing is needed... (e.g. for the most common browser/OS in the world).
Worked for me on a 2.5 year old OnePlus Nord 2T, both in Chrome and Firefox. Not a high frame rate, but perfectly usable, even on this pretty old mid-range phone.
