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 glitch-themed metroidvania built on exploration routing and pattern bosses.

Execution · Practiced Mastery
The fan-favourite sequel with harder levels and deeper secrets.
Axiom Verge leans Execution (Practiced Mastery); Donkey Kong Country 2: Diddy's Kong Quest leans Execution (Practiced Mastery).
Donkey Kong Country 2: Diddy's Kong Quest leans a little harder on execution, though the gap is small.
Axiom Verge
Boss dodging and platforming reward precision.
Donkey Kong Country 2: Diddy's Kong Quest
Demanding jump chains and animal-buddy control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Axiom Verge
No adaptive opposition.
Donkey Kong Country 2: Diddy's Kong Quest
Fixed enemy patterns, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Axiom Verge
World fixed and explorable.
Donkey Kong Country 2: Diddy's Kong Quest
Secret Lost World entrances hidden until found
Axiom Verge leans a little harder on optimization, though the gap is small.
Axiom Verge
Item routing and sequence breaks deeply learnable.
Donkey Kong Country 2: Diddy's Kong Quest
Routes, DK coins, and bonuses fully mappable
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.
