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

Execution · Practiced Mastery
A non-violent platformer testing grappling-swing timing through fixed first-person courses.

Execution · Practiced Mastery
One-thumb tap-timing precision over fixed courses with solvable coin routes.
A Story About My Uncle leans Execution (Practiced Mastery); Super Mario Run leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
A Story About My Uncle
Grappling-hook swings demand momentum timing and aim
Super Mario Run
One-handed tap timing for coin lines demands precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
A Story About My Uncle
No opponents exist at all
Super Mario Run
Auto-runner with no adaptive opponent; Toad Rally is asynchronous
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
A Story About My Uncle
Course layouts are fixed and visible
Super Mario Run
Courses are fixed and fully learnable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
A Story About My Uncle
Finding efficient swing lines through each cavern
Super Mario Run
Routing perfect coin runs is a solvable layout puzzle
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.
