Undertale : Sans fight

Genocide run final boss, Do you want to have a bad time. For anyone who hasn&played this game yet, don&take this as the games normal difficulty as the normal game is easy in comparison to this. I got this save file off someone else because i really didn&feel like grinding mobs and stuff to go the genocide path just to face this boss, because it looked challenging and fun. His last attack I&really bad at dodging lol fucking laser spin. also 6:04 the game glitches and it puts me off as the blue heart isnt supposed to fly up there.
