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

Execution · Practiced Mastery
A retro-Soviet action shooter mixing gunplay with light upgrade strategy.

Execution · Practiced Mastery
Sumi-e Zelda-like where a wolf goddess paints the world back to life.
Atomic Heart leans Execution (Practiced Mastery); Okami 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.
Atomic Heart
Shooting and dodging carry the combat.
Okami
Brush strokes and combat timing, forgiving
Atomic Heart leans a little harder on reads, though the gap is small.
Atomic Heart
Robot enemies follow scripted patterns.
Okami
Demons follow fixed patterns
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.
Okami
Authored world with no randomness
Okami leans a little harder on optimization, though the gap is small.
Atomic Heart
Upgrades and weapon crafting learnable.
Okami
Brush technique use, upgrades, and exploration
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.
