Try to keep the duo on one side of you to maximize your chi attacks. Once the shuriken ladies spawn, keep the pressure on them and use dragon kicks to force your way to them. They can’t shoot stars if they’re getting blasted across the roof!
The shuriken boss ladies posses every type of star attack, plus a red one that flings little daggers extremely quickly. These CAN be blocked.
Once your screen is filled with all types of femme fatales, get them to one side so they cluster together. This prevents them (especially the Shaa assassins) from really doing anything, and lets you line them all up for nice dragon kicks.
