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

Execution · Pure Mechanics
Terry Cavanagh's minimalist reflex gauntlet of rotating walls measured in seconds survived.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Super Hexagon leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
Super Hexagon leans clearly harder on execution.
Super Hexagon
Sub-second reactions at extreme speed, pure reflex ceiling
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.
Super Hexagon
No opponent, only walls
Super Mario Odyssey
No adaptive opponents whatsoever.
Super Hexagon leans a little harder on variance, though the gap is small.
Super Hexagon
Pattern order randomized from a known set
Super Mario Odyssey
Almost no randomness in level design.
Super Mario Odyssey leans clearly harder on optimization.
Super Hexagon
Pattern vocabulary is small, reaction is everything
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.
