A mid/difficult fight. You could mess around with things like mini-star count to reduce lag, although this makes the game easier. I personally suggest 9 if you are struggling with lag. Oh, and don't play this if you've never played Undertale. Pacifist (Mercy) is also impossible. Souls: Lime reverses attack colour effects. Cyan slows you. Orange speeds you up. Red does nothing. Enjoy!
USE THE CREATOR THINGY IT IS MWAH. Also, the hit boxes on the gaster blaster attack are kinda wonky. Take them out in the code by replacing attack 3's blocks with attack 2's blocks if you are having trouble because of lag.
