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
Experimenting with whimsical screens until their hidden interaction logic clicks.
P.T. leans Optimization (Pure Optimization); Samorost 2 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
Samorost 2
Pointing and clicking has no dexterity component
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
Samorost 2
No opponent of any kind exists
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
Samorost 2
Surreal puzzle logic is hidden until experimented with
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
Samorost 2
Each screen is a small solvable interaction puzzle
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.
