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

Execution · Practiced Mastery
A licensed platformer testing basic jump timing and level memorisation.

Execution · Pure Mechanics
A cute endless runner starring a dog dodging traffic.
Disney's Tarzan leans Execution (Practiced Mastery); Puppy Cross 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.
Disney's Tarzan
Jump timing and projectile tossing carry the platforming
Puppy Cross
Simple lane-dodging reflex timing
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
Puppy Cross
No opponents present
Puppy Cross leans a little harder on variance, though the gap is small.
Disney's Tarzan
Collectible placements fixed; nothing meaningfully random
Puppy Cross
Obstacle spawn randomness varies runs
Disney's Tarzan leans a little harder on optimization, though the gap is small.
Disney's Tarzan
Memorising level layouts and letter locations completes it
Puppy Cross
Minimal systems, casual endless runner
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.
