This is this message you'll encounter if you we're unable to beat your high-score:
Your score won't be stored in Database because the Arcade only saves users top score per Game.
The only known error within the arcade is "Your score has not been submitted" and it's encountered when a user causes the server to stop sending information after the send has already begun. This is commonly the result of refreshing the page just as it begins taking you to the high-scores page, regardless of whether or not you actually had a new score to submit.
