I made this a VERY LONG TIME AGO so do not expect much quality. The attacks are unbalanced and lead into each other weirdly, and the dialogue doesn't make much sense. But funny Press O to Press O No, you don't get to win. That's against the rules
The music was made by @segasonic101 , The Underfell Project, and Vesperr Sprites are from GG!Underfell (which isn't what this Underfell battle even is, I added it like 3/4ths of the way in) and made by RynoGG.
