Fixed an issue with the game progress JSON file after upgrading to a new version.
As you probably know, Tic-Tac-Toe always ends in a draw if neither player makes a mistake. To make the game more interesting Tic-Tac-GO! challenges you to play 10 games in a row as fast as you can without letting the AI player win. Don't expect to make three-in-a-row, just survive 10 games and take less time to be the best.
