"FELLSWAP was an undertale fangame by JoltfulUnderFaner2015, created somewhere round 2015 oct 20 as a demo. 1 month after undertale's release. the game was fully release in Dec 9 2023, the same date as undertale yellow's release.

the game was removed in Jul 11 2025 by toby fox himself, who told the creator that the game is a poorly made copy/clone of undertale and that some of the ideas & concepts are stolen."
