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 licensed platformer testing basic jump timing and level memorisation.

Execution · Practiced Mastery
Light twin-stick dodging through scripted robot arenas.
Disney's Tarzan leans Execution (Practiced Mastery); Kitten Squad 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.
Disney's Tarzan
Jump timing and projectile tossing carry the platforming
Kitten Squad
Twin-stick dodging and aiming is the whole challenge
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Disney's Tarzan
Jungle enemies run fixed simple patterns
Kitten Squad
Robot enemies follow simple scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Disney's Tarzan
Collectible placements fixed; nothing meaningfully random
Kitten Squad
Levels repeat identically between attempts
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Disney's Tarzan
Memorising level layouts and letter locations completes it
Kitten Squad
Weapon picks and learned layouts give modest edges
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.
