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 · Pure Mechanics
A marble-rolling platformer testing precise tilt control.

Execution · Pure Mechanics
Forgiving spectacle combat that lightly tests combo execution.
Marble Mountain leans Execution (Pure Mechanics); Star Wars: The Force Unleashed II leans Execution (Pure Mechanics).
Marble Mountain leans a little harder on execution, though the gap is small.
Marble Mountain
precise tilt-control marble navigation
Star Wars: The Force Unleashed II
Combo timing and dodges carry the spectacle combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Marble Mountain
no opponent, solo obstacle courses
Star Wars: The Force Unleashed II
Stormtroopers follow simple fixed scripts
Marble Mountain leans a little harder on variance, though the gap is small.
Marble Mountain
minor randomized obstacle timing
Star Wars: The Force Unleashed II
Encounters are scripted and identical every run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Marble Mountain
route and speed optimization per level
Star Wars: The Force Unleashed II
Upgrade choices barely matter against forgiving difficulty
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.
