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 more combat-forward sequel with sharper platforming demands.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Ori and the Will of the Wisps leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Ori and the Will of the Wisps leans a little harder on execution, though the gap is small.
Ori and the Will of the Wisps
Combat plus escape chases demand tight inputs
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Ori and the Will of the Wisps leans a little harder on reads, though the gap is small.
Ori and the Will of the Wisps
Scripted bosses, no human opponent
Super Mario World
Scripted Koopas adapt to nothing
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Ori and the Will of the Wisps
Deterministic encounters
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Ori and the Will of the Wisps leans a little harder on optimization, though the gap is small.
Ori and the Will of the Wisps
Shard loadouts and weapon choice tune playstyle
Super Mario World
Secret exits and route knowledge add a modest solvable layer
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.
