Oh, fantastic! I've tried rebuilding this for macOS half a dozen times, and never quite managed for one reason or another. And now you've brought it to the browser.
I might try adding reflections and translucency to ice someday.
If you want to play locally on macOS, here is a build. If it fails to run, it is likely the error "The requested video mode is not available" and can be run if connected to an external monitor (then you can disable fullscreen and launch without an external monitor).
