First, it didn't work in Firefox 89 on macOS due to CORS loading problems. Fortunately, I gave it a try in Chrome. There, the buttons "S" and "D" didn't work. But fortunately, the arrow keys worked. I'm happy I stuck through the first hurdles because this game is really great! Love the audio! Really like the visuals. And the gameplay is very enjoyable!
Unfortunately then again, the "R" button did not only reset the level but the whole game (including a loading delay of a few seconds). And also, I don't have a windows machine.
So I'll add to my collection, hoping that some of the quirks will be fixed (or a macOS build will be released) and enjoy it in an adequate manner. 👍
