The traditional level system has been replaced by a new star level system, which allows you to track your progress and earn badges as you advance. Badges are available at different levels, starting with 'Proficient.' More information about the star level system can be found by navigating to the menu and selecting 'Star level.' Additionally, we've added a new feature called 'Bet,' which allows you to earn XP when the user you've bet for wins a duel.
