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

A hidden-object hunt rewarding patient visual scanning of dense scenes.

A Castle Full of Cats leans a little harder on execution, though the gap is small.
A Castle Full of Cats
Pointing and clicking at cats, nothing more
Kentucky Route Zero
Player input amounts to clicking and dialogue selection only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Kentucky Route Zero
No opponent; choices shape tone not outcomes
A Castle Full of Cats leans a little harder on variance, though the gap is small.

Kentucky Route Zero
Negligible randomness; the world is a fixed authored space
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
