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
A point-and-click mystery testing deduction across hidden clues and conversation chains.
P.T. leans Optimization (Pure Optimization); The Blackwell Deception 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 Deception
Pointing and clicking has 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 Deception
Scripted story characters never adapt to you
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 Deception
Clues and dialogue paths are hidden 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 Deception
Cross-referencing notes and deducing the puzzle chain is the test
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.
