Hey there! This is Cheesehotdog's Underfell Hard Mode Sans fight! Remember, in Underfell, Sans is a pacifist boss, so sparing is necessary for the real ending. CONTROLS ------------- You already know the controls, don't you? And, if you are wondering, I never actually beat the fight, but I tested all the parts, and it is possible to complete and no hit.
Welcome! In this game, I took underfell sans and made him twice as difficult! I also messed with the text. P.S. Thanks to loganvcairns for the game and Toby Fox for Undertale.
