Undertale controls: Arrow keys to move stuff, [Z] to confirm, [X] to cancel and skip some text. ALSO, you probably want to have full HP when he uses his special attack, or else you will probably get rekt (you'll most likely get rekt first time you get to it anyway xD) Battle takes place on a genocide run, at the enterance to the CORE. Hold [Q] and press [R] to do a "True Reset"
