head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
Solving fixed grim puzzles to escape a facility, dexterity-free.

Optimization · Pure Optimization
A dark adventure game about a suicidal woman granted immortality to hunt five psychopaths.
Cayne leans Optimization (Pure Optimization); The Cat Lady leans Optimization (Pure Optimization).
The Cat Lady leans a little harder on execution, though the gap is small.
Cayne
Isometric point-and-click, no dexterity
The Cat Lady
Side-scrolling adventure controls require no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cayne
No adaptive threat in the facility
The Cat Lady
The Parasites are story antagonists, not adaptive opponents
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cayne
Story horrors are hidden until uncovered, then static
The Cat Lady
Mild unknowns in puzzle solutions on a blind playthrough
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cayne
Solving fixed environmental puzzles drives all progress
The Cat Lady
Adventure-game puzzles have fixed discoverable 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.
