Enter MUSIC ON as a name to enable music mode, which allows background music
in all stages to be played.
Gaining levels faster:
Place the character with the highest level on one team, then place the
character that you want to level up. Make sure the character you want to
level up has any bow. When in training mode, have the character with the
high level turn their back to the person with the low level. Then order the
character with the bow to attack. When you reach the same level as your
opponent, end training. You can add as many characters as desired, but the
number of characters to level up must be equal to the number of characters
that are of a higher level.
