Left Arrow Key or A to go to previous backdrop, Right Arrow Key or D to go to the next backdrop. How this one works is that you delete all the other backdrops, make your own music, add the name of your boss theme above the image of the character, and share it. DO NOT STEAL MUSIC FROM ANYTHING ELSE, I will ask you what you used to make said boss theme, if you have stolen it from somewhere and did not make it yourself you will not have your boss theme added to the game.
Notice: If the character name is in black, then it needs a boss theme, if it is red, it needs just a theme, not a boss theme, just a theme for when talking to said character. https://scratch.mit.edu/projects/210709519/#player voice lines.
