About

Undertale is a 2015 role-playing game created by American indie developer Toby Fox, in which the player explores the Underground and can choose to fight or spare the monsters they meet, with dialogue, characters, and the story changing based on those choices. This repository is a plain source-code dump, uploaded by someone who says they received what may be decompiled Undertale code from a third party and chose to share it; the uploader explicitly states they are not Toby Fox, Undertale's original creator. No platform, build instructions, or further context are given.
