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. ayo, this is probably the biggest one I've made. (while Soul Cat has only 40 costumes, Scratch Cat has 61 costumes, so whoever chooses him have fun with that)
I have redesigned Null twice now.
