Your strategy is a lot like mine for Absolute Radiance. Stick to the lower three platforms, dodge everything and wait for her to get close. Rinse and repeat.
The music is so good, love listening to the PV song in the OST, the ending is especially chilling. I hope I can fight PV one day, stuck on Sly for now. The fight just sound and look so badass and the hits sounds so hard and brutal!!!
