Underswap Papyrus

You find yourself in the Underground, wandering through, until you see a puzzle infront of you. It's a strange yet fascinating place... How is there Sun if this underground? A short skeleton sees you and helped you with said puzzle (unaware you are a human.) You're having a surprisingly good time solving the puzzles set up by a friendly skeleton named Sans. Then a taller skeleton in a orange hoodie showed up... [This can be affected by your actions and your choices. You can and will be judged by a certain skeleton.]
