My Undertale map

So this undertale map took me a year to finish. I know it isn't perfect, but it is mine and I love how it turned out :) I hope you enjoy it! Please tell me what you think as I have poured my heart and soul into it. Dramatic I know, but I wanted to make an undertale map like this ssince 2016. So yeah, just enjoy it and tell me what your favorite thing of the map was!

When the map started: Somewhere in May of 2025 I think. I'm not really sure.

When I finished it: The last time I worked on it was 7/13/2026, which is when I'm publishing it!

I wanted to make it large enough to seem like an actual huge cave, but not like an underground world, more like one of those huge underground caves with ecosystems people find. I'm sure you've seen them on the internet.

My favorite thing to make was the core. I love it!

Anyway, enjoy!
