Too many switching point of views and limelight?

I'm making a story where I switch the point of view and limelight between up to fifteen characters and still counting. Would that be too much?

I'd say yes. Keeping track of that would be a pain, for me at least. Maybe lessen the role of some or multiple stories from one perspective.

If you have to, label the viewpoint changes clearly.

Unless you are the incarnate god of characterization, it will just be confusing.

As long as each switch is clear about who is the new POV character, I see no reason why it shouldn't work.
