Polygon Universes : Switched Stories

Undertale is a turn based RPG game where you can spare your ennemies, it is made by Toby fox. It became so popular that the community made alternate universes (AUs), where the characters change personality or roles, and alternate timelines (AT), where it's a universe where some events happened and the story changed. As an example for an AT we can take Horrortale, Horrortale is Undertale after a Neutral run, the main character left the monster in the underground and left, their sanity degraded and they became insane to the point of cannibalism. Well now, I'm doing an alternate timeline of an alternate universe known as StoryShift (you can check all the details on internet am not going to explain everything).
