Press the green flag 2 projects in one day, wow(although this is the lamest project ever...)!
Ok, so just by listening, I can tell you're confused, but let me explain my simple "discovery" that a million people have probably already done. I made the notes appear in different sprites, therefore I could change the volume of one while the other is not changed, so you could use this to have a quieter "background" to the main melody. So, I hope this helps at least a few noteblockers out there, and see ya
