Click the flag, then click the faces to make a sound. The buttons with arrows are kinda like background music. To use those, press the key that is shown on the button.On the left arrow one, I combined 2 songs together.IF YOU WANT TO REMIX, YOU MUST: 1. Don't change anything (besides the extra sprite)! 2. Put a sprite on the line in the bottom right corner.
This based off of my Music Box thing only this has more sprites.
