First, I was definitely interested in the story. Even being as late as I am coming into this, I was able to follow along and get enough of the world elements to be able to understand what was going on.
I agree with the prior comments about pacing and trimming. I think some of this is related to the amount of detail you're giving us in the fights. The guy shooting both pistols, one at a time, then slamming them into his belt to reload, etc. Something else to consider here is that in many cases what is interesting about the fights is how people were feeling and reacting, and less of the cinematic re-telling of a fight scene. In other words, when I watch the Matrix, I love to see Neo shoot up the lobby and everyone in it. But when I'm reading about it, I'd rather be in the character's head.
I also think the overlapping times when switching the POV contributes somewhat to the pacing issues. Also the frequency of the POV changes introduces some challenges where I am having to re-orient myself to a new character very quickly and frequently. In the last Jester POV, you actually wound up recounting most of the fight from the Jester's POV, but didn't really give us a lot in the way of new information.
There were also a number of moments where I felt like you were trying too hard to interject some extra information. Someone made the maid and butler comment earlier. I also wonder where this is the latter part of your book, how some of this information isn't already known to the reader. The bit about "Jaime had trained himself to follow two conversations..." was one example that stood out for me. It knocked me out of the story.
I grind my teeth over saying anything about this, but I also wanted to call out some originality questions. "The Multiverse" struck me as something that we've heard a lot in the past decade or so, and it jarred me every time I read it. Also the "slow entry shield" thing has been done quite a lot. They're both cool ideas, but I worry about seeing them in anything new.
There's a whole lot of interesting stuff going on in there. Some sort of wild assassin thing that dresses like a jester, robots, evidently a woman made out of dark matter...? Very cool stuff. I'm looking forward to reading more. I hope my comments are helpful.
