About Undertale: Cataclysmic Timelines
gg/WheK8mcw2J being overhauled! This game is made with the UTMM kit made by Nikolander and A_RandomDoggo. Ignore the game's like ratio, its motly from skill issued ppl lol - Undertale: Cataclysmic Timelines is a game based off the UTMM Series, You can call it a sequel to 'UTMM Calamity', Even though UTMM Calamity was far worse than this game... - Currently Fully Supports PC, Mobile and Console - Advised to keep your volume low - 2x Gold/EXP at Weekends, Stacks with gamepasses. - Battles take 5 seconds to load because of people falling off the map, I know it's annoying but thats what happens when theres too much details on map - Keep in mind server limit is 6 due to lag.
