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 · Pure Mechanics
A precision-platforming metroidvania built around fluid traversal.
Blasphemous leans Execution (Practiced Mastery); Ori and the Blind Forest leans Execution (Pure Mechanics).
Ori and the Blind Forest leans a little harder on execution, though the gap is small.
Blasphemous
Punishing 2D combat and platforming
Ori and the Blind Forest
Precise platforming and bash-chain escape sequences
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Scripted bosses
Ori and the Blind Forest
Scripted enemies, no adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Static world
Ori and the Blind Forest
Fixed layouts, minimal randomness
Blasphemous leans a little harder on optimization, though the gap is small.
Blasphemous
Rosary bead builds and routing
Ori and the Blind Forest
Ability routing and shard builds matter
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.
