It works just like Undertale. -Arrow Keys to move and jump. -Blue means STOP. Orange means GO. -This is just one big attack, meaning you will have no chance to heal. -This project is made for players who have beaten Sans already.
Only the way the attacks were organized is mine. Everything else comes from loganvcairns, who is a great Scratcher. Check him out. Comment below if you beat it. (I playtested it and it is 100% possible to win without taking damage, and I tried not to do any cheap shots with Sans' attacks.)
