head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Execution · Pure Mechanics
A physics comedy about an octopus in a suit flailing through fatherhood without blowing his cover.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Octodad: Dadliest Catch leans Execution (Pure Mechanics); Super Mario World 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.
Octodad: Dadliest Catch
Deliberately clumsy limb controls are the whole challenge
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Octodad: Dadliest Catch
No opponents, just suspicion meters
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.
Octodad: Dadliest Catch
Physics wobble adds slapstick unpredictability
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Super Mario World leans a little harder on optimization, though the gap is small.
Octodad: Dadliest Catch
Simple objectives, little system depth
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.
