You weren't kidding about it chugging on mobile. I'm on a Google Pixel 6 and it crashed my browser :'D. Perhaps it can be used as a nice stres test for Ruffle. Also, I would appreciate some screenshots showing where and how Ruffle differs from Flash, it's not like I can install Flash plugin on a current browser and check for myself.
Ruffle is an open-source reimplementation of Flash player. The only differences there are stem from the fact that Ruffle is still very much a work in progress.
While you can't install a plugin any more, you can still install a standalone Flash player. I even have it on my M1 Mac. Works surprisingly well.
