head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
Moderate platforming execution through inventive but fixed mental levels.

Execution · Practiced Mastery
A retro-styled action platformer with pogo-stick combat.
Psychonauts leans Execution (Practiced Mastery); Shovel Knight leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Psychonauts
Platforming and psychic combat need moderate precision
Shovel Knight
Pogo combat and platforming need timing
Shovel Knight leans a little harder on reads, though the gap is small.
Psychonauts
Mental-world enemies follow fixed behaviours
Shovel Knight
Scripted boss patterns, not reads
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Psychonauts
Level layouts are fixed and quickly known
Shovel Knight
Deterministic stages
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Psychonauts
Collectible routing and power upgrades add light planning
Shovel Knight
Relic and upgrade choices shape runs
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.
