Bosses
Eleven fights, each built the same way: an announcement you can read, a fast and dangerous attack, then an opening. Hit a boss during its opening and it takes 1.5 times the damage; outside of it, only three quarters. Every attack has its own animation: the boss shows the blow coming during the warning, strikes, then stays open and spent for exactly as long as the opening lasts. Each fight opens on a short cinematic: letterbox bars, the camera turning to the boss, its title card.
