I think the Princess was a fun fight despite the camera jittering when she does that DBZ shit where she teleports everywhere in the arena, it's one of those boss fights where you can just go along and dance with the boss' attacks rather than taking the standard route. Reflecting back the homing shots before wailing on the princess was satisfying. Also that final boss track is damn nice (whole soundtrack goes hard, never thought an unfinished game would have such a banging soundtrack)
