You are Frisk, the eighth human in history to fall into the Underworld. Freaky monsters and skeletons, the typical game dwellers, do not look so frightening soon. Instead, they become loyal companions!
But it all depends on your choice. Befriend them, and they will stand by your side in difficult times. Fight them, and they will treat you with hostility. Think out every action because the minimal percent of LOVE is critical for the outcome of the story. Enjoy the play, and don’t forget to save your progress.
