How To Play (READ EVEN IF YOU'VE PLAYED UNDERTALE) When you are the Red Soul (Red Heart Shape) , WHITE attacks will hurt you if you touch them, and ORANGE attacks, if you MOVE through them they WONT hurt you. But BLUE attacks, DON'T move through them and they won't hurt you. But GREEN attacks will HEAL you. Now that I told you about The RED soul, we'll talk about the LIME soul, which is a lot more simple to explain since we discussed the RED soul. So the LIME soul is like the RED soul, but the attack affects are reversed. So don't move through ORANGE attacks, move through BLUE attacks, WHITE attacks will heal you, and GREEN attacks will hurt you. Remember that during this battle. Oh, I also wanted to say that this battle takes place after the sans fight in Undertale's Genocide route. So you can't spare Chara in this battle.
