took a peep into what mitch is and assuming you're online for the entire duration of playing, I'd deff wait to see if it's an issue accessing resources from itch n their end. CORS means cross origin resource sharing: for all my games, the CSS has to import resources from fontawesome in order to display the icons. It seems at least possible that the app is having trouble with the mitch > itch >third party > itch > mitch pipeline when it comes to asking for resources, which could involve many different games if they're using imports from other websites instead of directly packaging all assets.
