Dear user, sometimes because of file size, connection speed or something else there are errors while uploading games via our website. We are trying to identify and address all possible issues.
Meanwhile, please use some other website for uploading your game like
https://wetransfer.com/
https://files.fm/
or Google Drive, Dropbox or any other similar service.
Then just send us a link with game description and screenshots to
info at fgn dot me.
Thank you for understanding.
