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 · Light / Casual
Cheerful physics platformer about a kicking blob toppling a capitalist conspiracy.

Execution · Practiced Mastery
Light web-swinging execution over a scripted open-world checklist.
Pikuniku leans Execution (Light / Casual); Spider-Man 3 leans Execution (Practiced Mastery).
Spider-Man 3 leans a little harder on execution, though the gap is small.
Pikuniku
Floppy kicks and hops, gently imprecise
Spider-Man 3
Swing control and combo timing carry the combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Pikuniku
No adversary anywhere
Spider-Man 3
Enemies follow fixed scripts, nothing models you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Pikuniku
Short authored world with few surprises
Spider-Man 3
Open-world missions are static once discovered
Spider-Man 3 leans a little harder on optimization, though the gap is small.
Pikuniku
Simple puzzles with obvious solutions
Spider-Man 3
Upgrade paths and mission objectives are shallowly solvable
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.
