computer port: https://scratch.mit.edu/projects/968007912/ The tile buttons: makes the current player sing in the direction you pressed The blue button: it switches who turn it is (the project will start as the opponent as default if your gonna do any songs that bf starts first) The green button: makes both people sing it The Red button/the trash: deletes the whole chart “Double-click flag so that the music syncs! You can replace characters by going into their costumes and replacing the poses with your characters' poses. You can also change some of the animation code if you want it to look different.”
I used the chart block made by @ jd114 project and made it functional with mobile controls
