Creator Comment
Wow! You know Sans! For those who don't, Sans is the final boss of the Genocide Route, one of the three main routes in Undertale. By the way, he is re.al.ly.hard. With his vicious patterns and dodging every attack, he seems impossible to beat, but the developers put in a weakness: he gets tired.
