Recently starting playing around with mod combination mostly for jokes but I ended up kinda getting into using HDHRFL, it's a combination I only really see on Kantan and Futsuu but not never exceeding Muzukashii if it even does get plays with those mods itself. I can understand though as it's not the most fun admittedly since you're relying solely off memory, Currently have FC'ed two Muzu/Oni-ish difficulties and I don't really plan to do it often since it's very mentally draining but i kind of recommend at least giving it a try
