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

Optimization · Pure Optimization
A tactile toy-box puzzler testing playful experimentation with hidden mechanisms.

Optimization · Pure Optimization
A dark adventure game about a suicidal woman granted immortality to hunt five psychopaths.
Gnog leans Optimization (Pure Optimization); The Cat Lady 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.
Gnog
Poking and spinning toy heads requires 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.
Gnog
The toys are charming clockwork, not minds
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.
Gnog
Each head's mechanisms are unknown until fiddled with
The Cat Lady
Mild unknowns in puzzle solutions on a blind playthrough
The Cat Lady leans a little harder on optimization, though the gap is small.
Gnog
Discovering each contraption's interaction sequence is the puzzle
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.
