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 dark puzzle-platformer about a tiny girl in a grotesque world.

Optimization · Practiced Mastery
Painterly cinematic puzzle platformer about a girl and her cat-like companion.
Little Nightmares leans Execution (Practiced Mastery); Planet of Lana leans Optimization (Practiced Mastery).
Little Nightmares leans a little harder on execution, though the gap is small.
Little Nightmares
Stealth platforming demands timing.
Planet of Lana
Gentle platforming and chase sequences
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Little Nightmares
Enemies are scripted.
Planet of Lana
Machines follow scripted patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Little Nightmares
Minimal randomness.
Planet of Lana
Fully authored puzzles
Planet of Lana leans a little harder on optimization, though the gap is small.
Little Nightmares
Routes have fixed solutions.
Planet of Lana
Companion-command puzzles have single 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.
