head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
A grim 2D action metroidvania steeped in religious horror.

Execution · Practiced Mastery
A Pixar-styled action adventure about a spirit guide cleansing a corrupted forest.
Blasphemous leans Execution (Practiced Mastery); Kena: Bridge of Spirits leans Execution (Practiced Mastery).
Blasphemous leans a little harder on execution, though the gap is small.
Blasphemous
Punishing 2D combat and platforming
Kena: Bridge of Spirits
Parry and dodge timing in boss fights
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Scripted bosses
Kena: Bridge of Spirits
Corrupted spirits are fully scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Static world
Kena: Bridge of Spirits
World is fixed and explorable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Rosary bead builds and routing
Kena: Bridge of Spirits
Rot ability usage and boss pattern learning
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
