head to head
Neither is simply harder - they are hard in different places. A Building Full of Cats demands more variance; Life is Strange demands more optimization.

Variance · Systems & Chaos
A hidden-object hunt that tests visual search until every cat location is known.

Optimization · Systems & Chaos
A teenage drama built around rewinding decisions to map which choices actually alter the scripted outcome.
A Building Full of Cats leans Variance (Systems & Chaos); Life is Strange 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.

Clicking spotted cats takes no dexterity
Life is Strange
Rewind mechanic removes virtually any failure state
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Life is Strange

Life is Strange
Rewind obscures which choices are truly consequential

A Building Full of Cats
Systematic screen-scanning is the only strategy layer
Life is Strange
Understanding consequence chains enables deliberate dialogue path planning
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.
