I got this error after I uploaded my game.

There was a problem loading your project:

Zip contains file that is too large (Build/_builds.data.unityweb)

Please try deleting the ZIP file and uploading another one.


Its not even very big.  335744KB

335 megabytes is very big for a file that’s going to be downloaded to be played directly in the browser. I highly recommend that you consider making your game downloadable if you have a large game. There’s more information here: https://itch.io/docs/creators/html5#zip-file-requirements

You may want to investigate if you have unomptimized or unused assets in your game bundle that you can remove if you believe that your game is small.
