Tbh, I don't have much problems with the difficulty when it's about enemies or bosses. Yeah, I'm dying over and over, but that's because I have two left hands and fingers with glass bones.
But I do have a problem with the parts where you can get stuck or you progressed "too fast"... I don't know if that's because of the difficulty, or just the map design not trying to stop me to "progress wrong" (which would be weird because the hackrom locks your progress behind these computers that can unlock the doors anyways), but I did experimented these stucks because I "progressed wrong" too many times, is kinda bothering and I truly don't want to check a guide (If there's even one), mostly because it would kill the magic of exploring the map by myself.
