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
A first-person horror about a cult in the Arizona wilderness.

Execution · Pure Mechanics
A cute endless runner starring a dog dodging traffic.
Outlast 2 leans Execution (Practiced Mastery); Puppy Cross leans Execution (Pure Mechanics).
Puppy Cross leans a little harder on execution, though the gap is small.
Outlast 2
Chase sequences demand quick movement.
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.
Outlast 2
Cultists follow scripts.
Puppy Cross
No opponents present
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Outlast 2
Some encounter variability.
Puppy Cross
Obstacle spawn randomness varies runs
Outlast 2 leans a little harder on optimization, though the gap is small.
Outlast 2
Route memorization aids survival.
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.
