The browser version seems to be stuck loading for me (I'm seeing a Unity icon with a progress bar that's 90% full). I'm on macOS 11 rn so I can't download the game either...
On windows too. I see "Error: Uncaught ReferenceError: unityFramework is not defined" in browser console.
Yes Unity recently updated their WebGL and itch.io can't run unity WebGl now.
It ran my game, pretty well
And i used unity
