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

Optimization · Pure Optimization
A dark adventure game about a suicidal woman granted immortality to hunt five psychopaths.

Optimization · Pure Optimization
Methodically dissecting intricate puzzle boxes whose mechanisms are fully solvable.
The Cat Lady leans Optimization (Pure Optimization); The Room Three 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.
The Cat Lady
Side-scrolling adventure controls require no dexterity
The Room Three
Rotating and prodding mechanisms takes no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Cat Lady
The Parasites are story antagonists, not adaptive opponents
The Room Three
The Craftsman is narrative dressing, not an adaptive mind
The Room Three leans a little harder on variance, though the gap is small.
The Cat Lady
Mild unknowns in puzzle solutions on a blind playthrough
The Room Three
Hidden mechanisms are unknown until inspected, then fixed
The Room Three leans a little harder on optimization, though the gap is small.
The Cat Lady
Adventure-game puzzles have fixed discoverable solutions
The Room Three
Each puzzle box is a fully solvable mechanical system
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.
