Double-click the 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. You can also change the note skin of each arrow set now
Thanks to @Alox2178 for the Pico sprite [this is the better option than me animating it fully, trust me.] Had to censor a bit of the song. The Notes for the opponent flash like crazy about 1 minute and a half in.
