I wondered why it was taking so long to unzip the project. You seem to have uploaded your entire project including modules, repo, etc. to Itch.
When distributing your game, you don't really want to zip up and upload the entire project. You want to export your project (usually to an index.html file and some dependencies) then zip and distribute that. That way you can play the game at a click of the index.html file (or ideally play directly in the browser), and also the resulting .ZIP will be way way smaller.
I don't have anything on this machine that can run a React project, so I can't play the game at this time, but if you can find a way to export it and reupload I'd be happy to check it out.
Cheers.
