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 · Pure Mechanics
Retro Studios' notoriously tough revival of Donkey Kong Country with relentless set-piece levels.

Execution · Pure Mechanics
A horizontal shoot-em-up built around time manipulation and bullet-hell dodging.
Donkey Kong Country Returns leans Execution (Pure Mechanics); Sine Mora leans Execution (Pure Mechanics).
Sine Mora leans a little harder on execution, though the gap is small.
Donkey Kong Country Returns
Demanding rocket-barrel and mine-cart sections, strict timing
Sine Mora
precise bullet-hell dodging is the whole test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong Country Returns
Scripted hazards, no adaptation
Sine Mora
scripted enemy patterns, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong Country Returns
Hidden puzzle pieces, fixed once found
Sine Mora
minimal randomness in patterns
Donkey Kong Country Returns leans a little harder on optimization, though the gap is small.
Donkey Kong Country Returns
KONG letters and time attack routes are learnable
Sine Mora
time-manipulation and route memorization
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.
