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.

Optimization · Practiced Mastery
A four-player Wii Kirby romp gathering ship parts for the stranded alien Magolor.

Execution · Practiced Mastery
A dark puzzle-platformer about a tiny girl in a grotesque world.
Kirby's Return to Dream Land leans Optimization (Practiced Mastery); Little Nightmares leans Execution (Practiced Mastery).
Little Nightmares leans a little harder on execution, though the gap is small.
Kirby's Return to Dream Land
Easygoing main game; EX mode adds modest demands
Little Nightmares
Stealth platforming demands timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby's Return to Dream Land
Bosses are pattern-scripted
Little Nightmares
Enemies are scripted.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby's Return to Dream Land
Energy sphere hiding spots are static secrets
Little Nightmares
Minimal randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby's Return to Dream Land
Super ability timing and sphere collection are solvable
Little Nightmares
Routes have fixed solutions.
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.
