The Music Player is the screen on the interface where you can choose the theme music that is playing at the moment. The music is unlocked as you play the game and exploring new places and contents.
Players can click on the loop button at the top of the screen. If it is on, the track played on that moment will automatically repeat itself. Players can also click on green titles to choose which track to listen to. Titles in red have not been unlocked, and thus cannot be played.
