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

A story-first adventure with gentle item-puzzle logic as its only test.

Optimization · Pure Optimization
A dark adventure game about a suicidal woman granted immortality to hunt five psychopaths.
Back to the Future: The Game 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.
Back to the Future: The Game
Telltale point-and-click, zero 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.
Back to the Future: The Game
Characters follow the episodic script
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.
Back to the Future: The Game
Puzzle solutions are hidden until found
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.
Back to the Future: The Game
Light item-logic puzzles drive each episode
The Cat Lady
Adventure-game puzzles have fixed discoverable solutions
