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 retro-Soviet action shooter mixing gunplay with light upgrade strategy.

Execution · Practiced Mastery
A grim 2D action metroidvania steeped in religious horror.
Atomic Heart leans Execution (Practiced Mastery); Blasphemous leans Execution (Practiced Mastery).
Blasphemous leans a little harder on execution, though the gap is small.
Atomic Heart
Shooting and dodging carry the combat.
Blasphemous
Punishing 2D combat and platforming
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Atomic Heart
Robot enemies follow scripted patterns.
Blasphemous
Scripted bosses
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Atomic Heart
Encounters largely fixed.
Blasphemous
Static world
Blasphemous leans a little harder on optimization, though the gap is small.
Atomic Heart
Upgrades and weapon crafting learnable.
Blasphemous
Rosary bead builds and routing
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.
