Red Star(s)

[Shinji16]

A near full combo, getting all the power ups (to keep your combo), and making sure to hit 10x several times using Chi while at 5x thanks to a multiplier power up.

Getting a good combo seems to be the biggest factor. If you get a 200+ combo on a song, you're in good standing for a red star.

i wondered that about that too. i have red stars for all tracks on master, and some on expert. my advice so far is just don´t miss the combo, your final score change a lot even if you miss one or two thugs.

Once I've got 6 stars while missing a couple of enemies. So getting full combo or hitting all enemies is not required. And so I don't see other options other than score-based.

I received a red star for a song and based off my performance, I'm gonna assume that it's related to my score. Would appreciate a confirmation and criteria(s) needed to obtain red stars.
