Thanks for the feedback, this also happened to yours when I tested it here, it gave a download error, but I tried again letting it load for longer and it went past the loading screen, this must be because itch.io loading a WebGL can set something that It's browser heavy on itch.io, but in general it worked for everyone who tested it even on weaker computers, just let it load a little longer and then refresh the page if it freezes while loading.
