head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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

Execution · Pure Mechanics
Light-gun aim speed against fixed enemy waves on Mario-themed rails.
Octodad: Dadliest Catch leans Execution (Pure Mechanics); Yoshi's Safari 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
Yoshi's Safari
Super Scope aim speed and accuracy is the entire test
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
Yoshi's Safari
Enemies attack on fixed choreography
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
Yoshi's Safari
Stages play identically every run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Octodad: Dadliest Catch
Simple objectives, little system depth
Yoshi's Safari
Memorising boss weak points and wave order helps
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.
