head to head
Neither is simply harder - they are hard in different places. Super Mario Odyssey demands more optimization; Time Surfer demands more variance.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.

Execution · Pure Mechanics
An endless runner where players slow and speed time to dodge obstacles.
Super Mario Odyssey leans Execution (Pure Mechanics); Time Surfer leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Time Surfer
precise timing-based reflex dodging
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
No adaptive opponents whatsoever.
Time Surfer
no opponent, solo endless runner
Time Surfer leans clearly harder on variance.
Super Mario Odyssey
Almost no randomness in level design.
Time Surfer
procedurally generated obstacle patterns
Super Mario Odyssey leans clearly harder on optimization.
Super Mario Odyssey
Moon routes and movement tech learnable.
Time Surfer
minimal strategic depth beyond reflexes
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.
