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

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

Execution · Practiced Mastery
A stylish anime bullet-hell shooter about cleaning up poison.
Blasphemous leans Execution (Practiced Mastery); Poison Control leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Punishing 2D combat and platforming
Poison Control
Bullet-hell dodging and aiming precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Scripted bosses
Poison Control
Fixed boss patterns, no adaptation
Poison Control leans a little harder on variance, though the gap is small.
Blasphemous
Static world
Poison Control
Some enemy spawn randomness
Blasphemous leans a little harder on optimization, though the gap is small.
Blasphemous
Rosary bead builds and routing
Poison Control
Build/route optimization secondary
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.
