Have you uploaded the files of the game? Is there something in the settings that was missed? There are options like
Hide this file and prevent it from being downloaded
Which would not show the file on the game’s page.
Looking at your free game, it seems you are using Google Drive to distribute those files. Maybe that’s causing an issue? I also don’t understand why, uploading a zip archive with all the game’s files is far better than a link to Google Drive that does the same thing.
