Description (written by the developer; not a statement by this register)

THIS GAME HAS BEEN CANNED! It wasn't fun to work on the game anymore after 2 years of non-stop revamping. If you're disappointed, fear not. Because an upcoming game is being released by the same people you all know and love (us) Undertale Multiverse Destruction Remake is still in development. Gamepasses from UT:CM Will be transferred over to UTMDR. Goodbye Undertale Collapsing Multiverse!
