Boss help

[Zipplip]

hey so I'm trying to get three star rank on the King Boo fight and I can't seem to figure out how. Can someone please help me out?

Don't get hit and try and watch the shadows and warning signs. Make sure that you also complete it as fast as possible as well. I honestly don't know what else to tell you. I 3 stared him first try and I got hit once or twice.

well at least tell me how much damage I can take and still get three stars. It's mainly the chase scenes that I get hurt on
