WARNING, HUMAN! THIS IS NOT GAURANTEED TO BE "ULTIMATE". hey. so this is just a battle engine i made, ripped straight from my undertale last breath remake. (which, you can find on my gamejolt.) so to use it, you have to download the SB3 and open it in TURBOWARP. https://www.mediafire.com/file/7y9a39kry4x5is5/UNDERTALE_Battle_Engine.sb3/file and there's instructions in the project. so just look at those. if you have any concerns or are confused, just ask me.
~CREDITS~ I forgot who made a lot of the stuff but credits go to them (i didn't make the box, soul, hp, text, alphyslovania, or the papyrus sprite) Text engine ~ @PainInCode Papyrus sprite ~ @InkDustSans both are goated everyone else is goated too
