We have a game deployed for the Mac and it runs.
We zipped it in our Mac.
To test to see if the zip file was corrupted, we unzipped the original file and it worked.
We uploaded that zip file to Itch.
We downloaded the zip file from itch and unzipped it.
When we load the game, it gives an error message:
Please Move the Game.app to a different folder."
We moved the Game.app to the application folder and also the desktop, but got the same error messages.
