In this thrilling simulator, you can play for either Sans or Frisk. And both characters will be involved in an intense fight. The heroes have different powers. A skeleton can apply a number of attacks, while Frisk can only stab his opponent with a knife. Select whom you want to play for and enter this cruel confrontation. Everything will depend on your attentiveness and agility. Try both roles to see where you can perform better. But note that Sans remains really dangerous and you must always keep an eye on him.
