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 meta puzzle comedy testing lateral thinking against deliberately misleading interface tricks.
P.T. leans Optimization (Pure Optimization); There Is No Game 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
There Is No Game
Clicking is trivial by design
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
There Is No Game
The narrator is scripted comedy, not an adapting mind
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
There Is No Game
Surprise fourth-wall tricks are hidden until discovered once
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
There Is No Game
Lateral-thinking puzzles have fixed clever solutions
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.
