"Every boss must be beatable with only a dagger": Gamasutra and Kotaku on Bloodstained's boss design rule

Based on a Gamasutra interview with Koji Igarashi, Kotaku reported on the rule behind the bosses of Bloodstained: Ritual of the Night.

Whoever built a boss had to prove it could be beaten using only a dagger and without taking a single hit. The rule exists to rule out unfair difficulty and keep attack patterns honest. It was the team’s standard for boss fights that feel demanding yet fair.
