The user's account is 1 week old and is the supermod of the game, this means the game has only been added recently. A user has 2 weeks to set up the game's board, or the game is deleted. You can either wait for the game to be removed and then re-submit the game, or you could head over to the Mod request page and ask to be added for Hero Siege. Since the user hasn't been online pretty much since the account was made, and has no accounts attached to his account, it will likely be accepted.
