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 · Pure Optimization
Colour-painting terrain puzzles that resolve to finding the intended solution.

Optimization · Practiced Mastery
A forgiving platformer testing light execution and exploration routing through fixed level designs.
Nihilumbra leans Optimization (Pure Optimization); Psychonauts 2 leans Optimization (Practiced Mastery).
Psychonauts 2 leans a little harder on execution, though the gap is small.
Nihilumbra
Some platforming timing, but forgiving throughout
Psychonauts 2
Moderate platforming and combat timing, forgiving by design
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Nihilumbra
Enemies cannot be fought or read, only avoided
Psychonauts 2
Solo adventure with no adaptive opponent anywhere
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Nihilumbra
Hand-designed puzzles with nothing random
Psychonauts 2
Level layouts and collectibles are fixed once seen
Nihilumbra leans a little harder on optimization, though the gap is small.
Nihilumbra
Choosing which colour solves each terrain puzzle is the game
Psychonauts 2
Routing collectibles and matching psychic powers to encounters
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.
