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 physics control for record times.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Marble It Up! leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
Marble It Up! leans a little harder on execution, though the gap is small.
Marble It Up!
Frame-perfect marble control and boosting decide every run
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Marble It Up!
Solo time-trials - no opponent to predict
Super Mario Odyssey
No adaptive opponents whatsoever.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Marble It Up!
Physics are deterministic, nothing random
Super Mario Odyssey
Almost no randomness in level design.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Marble It Up!
Finding optimal lines for record times rewards mastery
Super Mario Odyssey
Moon routes and movement tech learnable.
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.
