I was wondering why the game files are so massive, but once I downloaded it I realized why. You actually shouldn't be submitting or uploading your project files, but instead build the game within Unity, and upload the build. Otherwise we'll need to download Unity with the version you're working the game on, and there might be errors, and probably a lot of people will end up not trying, because it takes a lot of time to do.

Unfortunately, I haven't tried it. Your Unity version is 2021.2, but my installed one is 2022.2. I could download the 2021.2 version, but my disk is running out of space. Perhaps you can build your game, host the files (maybe Google Drive?) or maybe create a new itch.io page and put the built game in perhaps? I'd give it a try, your game seems interesting based on the screenshots and descriptions.
