This is a dimensional exploration mod for Undertale. Although my personal technical skills are limited, I strive to recreate and expand the world of Undertale in Minecraft in my own way.

Find a small hill in the Overworld. You need to use a Magic Stone — crafted from diamonds, bottles o' enchanting, and three emeralds — to activate the bedrock portal hidden inside the hill, which will take you to a mysterious Underground world.

Version 0.1 is very rudimentary, yet it already features two new biomes, a full set of new equipment, several new materials, four new generated structures, and a boss worthy of your challenge — Undyne — waiting for you to discover.

Hereby declared: Part of the code is AI-assisted.

Although there are some limitations, I have decided to continue developing on MCreator. I will combine it with IntelliJ IDEA and try my best to complete the 1.0 official release (waterfall area complete and snowy plains test).
