i actually... don't get the issue with muffet? How people find her difficult, that is.
It's basically taking the bullet hell mentality and applying it to something like a rhythm game. Instead of making sure you catch the bullets, just make sure you dodge them. Ignore any bullets that are not currently on your lane. If you find a path to go through, do it.
Half of my vision is permanently blurry to the point of blindness and I get dizzy when things start moving incredibly fast. Most parts of this game so far have been fine, but Muffet turns on all the 'get dizzy and die' switches in my head.
It really is a good pain. Muffet is a good pain.
