I made a generic leaderboard site people can use to make leaderboards for their games and so i added online score submission for the game. The score submission works by first achieving an high score and then the game will generate a QR code which you can scan using your phone. The Scanned QR Code will open a website where you can fill in your name, submit the score and view other people's high scores. You can view the leaderboards here. Have fun!
