When I first played the
boss fight, I felt like it was kind of ill-conceived. It may still be, but after going through it a second time, I've warmed up to the fact that the entire fight is basically a puzzle. The first time I played it, I was kind of running around like a chicken with its head cut off, and now on NG+ knowing how to approach it -- I didn't use a single healing item, whereas the first time through I went through all 20 trying to figure out what to do and how to do it.
I think it's a pretty cool fight now, even if it ends up being the first fight on NG+ which I feel is basically pushover levels of easy.
