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 · Pure Mechanics
A cute endless runner starring a dog dodging traffic.

Execution · Practiced Mastery
A cinematic action sequel through Viking-age Iceland.
Puppy Cross leans Execution (Pure Mechanics); Senua's Saga: Hellblade II 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.
Puppy Cross
Simple lane-dodging reflex timing
Senua's Saga: Hellblade II
Set-piece combat needs timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Puppy Cross
No opponents present
Senua's Saga: Hellblade II
Encounters are scripted.
Puppy Cross leans a little harder on variance, though the gap is small.
Puppy Cross
Obstacle spawn randomness varies runs
Senua's Saga: Hellblade II
Minimal randomness.
Senua's Saga: Hellblade II leans a little harder on optimization, though the gap is small.
Puppy Cross
Minimal systems, casual endless runner
Senua's Saga: Hellblade II
Linear progression, few systems.
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.
