Hmmm. Looking through the console output, I don't see any errors being thrown from the game. For why it's freezing,it's probably lines 15-17, but those JS files aren't from the game and I'm not sure where they're coming from. Since you tried it in multiple browsers it doesn't seem likely that it's an extension. It could be a network problem, I know Itch has quite a few problems with VPNs if you're using one of those.
You might try to use the offline version and see if that resolves your issue, although it's not the easiest thing in the world to set up.
