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 forgiving platformer testing light execution and exploration routing through fixed level designs.

Optimization · Pure Optimization
Tests creative tool-combination puzzle solving across a metroidvania sandbox.
Psychonauts 2 leans Optimization (Practiced Mastery); Supraland: Six Inches Under leans Optimization (Pure Optimization).
Psychonauts 2 leans a little harder on execution, though the gap is small.
Psychonauts 2
Moderate platforming and combat timing, forgiving by design
Supraland: Six Inches Under
First-person platforming and light combat need modest precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Psychonauts 2
Solo adventure with no adaptive opponent anywhere
Supraland: Six Inches Under
Solo world with no adaptive adversary
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Psychonauts 2
Level layouts and collectibles are fixed once seen
Supraland: Six Inches Under
Secrets are scripted-but-unknown until discovered
Supraland: Six Inches Under leans a little harder on optimization, though the gap is small.
Psychonauts 2
Routing collectibles and matching psychic powers to encounters
Supraland: Six Inches Under
Chaining ability tools into puzzle solutions is the core test
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.
