Undertale Error Sans battle

Description

Credit to pococikapusta for the Undertale simple battle creator this was made on. It is one of the best projects I have ever seen. Please, if you play this pococikapusta, please comment on your thoughts on this battle. I really hope this gets into the battle of the week studio, but if not, that's okay.

Instructions

YES I KNOW THE MOVEMENT IS BROKEN. Scratch Update 3.0 released a couple years back broke this project. This battle takes place after the genocide run. You have killed every monster, you and Chara erased the game and there is nothing left. Or so you thought. Meant to be really hard.
