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 · Systems & Chaos
Uncovering hidden item-puzzle solutions along a fixed time-travel story path.
The Cat Lady leans Optimization (Pure Optimization); The Silent Age leans Optimization (Systems & Chaos).
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 Silent Age
Pointing and clicking carries no physical test
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 Silent Age
A fixed story; nothing adapts
The Silent Age leans a little harder on variance, though the gap is small.
The Cat Lady
Mild unknowns in puzzle solutions on a blind playthrough
The Silent Age
Puzzle solutions are hidden information until discovered
The Cat Lady leans a little harder on optimization, though the gap is small.
The Cat Lady
Adventure-game puzzles have fixed discoverable solutions
The Silent Age
Item-combination logic converges to a single known path
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.
