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 · Practiced Mastery
Light twin-stick dodging through scripted robot arenas.

Execution · Practiced Mastery
One-thumb tap-timing precision over fixed courses with solvable coin routes.
Kitten Squad leans Execution (Practiced Mastery); Super Mario Run leans Execution (Practiced Mastery).
Super Mario Run leans a little harder on execution, though the gap is small.
Kitten Squad
Twin-stick dodging and aiming is the whole challenge
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.
Kitten Squad
Robot enemies follow simple scripts
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.
Kitten Squad
Levels repeat identically between attempts
Super Mario Run
Courses are fixed and fully learnable
Super Mario Run leans a little harder on optimization, though the gap is small.
Kitten Squad
Weapon picks and learned layouts give modest edges
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.
