head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
Decoding deliberately obscure puzzle triggers inside one repeating haunted hallway.

Optimization · Pure Optimization
Investigative puzzle-solving through dialogue and clue cross-referencing in a fixed story.
P.T. leans Optimization (Pure Optimization); The Blackwell Epiphany leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
P.T.
Walking a looping hallway - no dexterity test
The Blackwell Epiphany
Pointing and clicking carries no physical ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
P.T.
Lisa's hauntings trigger on hidden scripts, not adaptation
The Blackwell Epiphany
A fixed narrative with no adaptive adversary
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
P.T.
Obscure trigger conditions are hidden information to map
The Blackwell Epiphany
Clues are scripted-but-unknown until investigated
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
P.T.
Deciphering the cryptic final puzzle is the entire game
The Blackwell Epiphany
Cross-referencing names and notebook leads solves every case
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.
