This is the part in Gaster Fight II when Gaster uses Sans, except it's extended and changed a bit. Dodge everything. Also, an extra rule only in this one, Red attacks do two damage, instead of one. When touching blue, stop moving and you won't take any damage. When touching orange, you take damage if you stop moving. WARNING: You'll die a lot. Difficulty #5: _____death
I used images from undertale and some fan-made stuff. Also music from undertale.
