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
Decoding obtuse fixed puzzle chains hidden behind surreal imagery.
P.T. leans Optimization (Pure Optimization); Rusty Lake Paradise 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
Rusty Lake Paradise
Clicking scenes requires no dexterity
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
Rusty Lake Paradise
A scripted surreal story; nothing adapts
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
Rusty Lake Paradise
Obtuse solutions are hidden information on first play
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
Rusty Lake Paradise
Each plague ritual is a fixed puzzle chain to decode
