Ask for the shape of the challenge.

Each boss is a fixed piece of choreography that you learn by dying to its second phase forty consecutive times.

Parry-first combat with windows tight enough that blocking on reflex fails and blocking on rhythm works.

There is no block button — parrying is a direction plus an attack, aimed at the incoming blow, and the game tells you this once and then assumes it.

The EMMI zones are one-hit deaths with a counter window measured in frames, and the bosses expect dodges on reaction rather than pattern.

Every death ages you, and an old master dies in two hits. The run-level economy is what punishes learning a boss the slow way.

Sekiro’s deflection on a 2D plane. Chip damage means blocking is not a plan, and every boss is a rhythm you learn on frames rather than a health bar you widdle down.

Rhythm violence at speeds that stop being readable. The later levels are memorised rather than reacted to, whatever it feels like at the time.

One hit kills you and one hit kills them, and the retry is instant. Each room is a plan you rehearse at speed, not an endurance test.

Bullet-hell reflexes bolted to roguelike stakes — the two hardest things to hold simultaneously for two uninterrupted hours.

One hit kills, restarts land in under a second, and momentum is mandatory — stopping to think is usually the thing that kills you.
