Just random nitpicks: The "interact with me" emoji is hard to make out, looks like a glitch at first. Emojis should be images, for both consistency and making sure people don't get boxy question marks if their browser can't render. "toggle fullscreen" is off-center vertically. The demo frame is messed up in Edge. The text in the about page needs a max width. Like others mentioned the demo is a bit overwhelming, it also has some minor UX issues and is generally the weakest link design wise at the moment.
