I've done it again. The game's consumed me whole and doesn't want to let me out. Oh well. *small spoiler warning* So, after choosing to kill everyone in sight, Sans, one of the skeleton brothers, is the final boss. He doesn't look too intimidating, but he puts up one hell of a fight. If you can survive, you'll be able to deal a fatal blow after he falls asleep (that lazy bastard can never stay awake, even to save his life). *end of spoilers* get this song on the DETERMINATION EP: https://kazenoabs0.bandcamp.com/album/determination
