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

Optimization · Light / Casual
A first-person horror about exploring a haunted Prussian castle.

Amnesia: The Dark Descent leans Optimization (Light / Casual); Travellin Cats in Jingle Jam leans Variance (Light / Casual).
Amnesia: The Dark Descent leans a little harder on execution, though the gap is small.
Amnesia: The Dark Descent
Stealth and hiding, low demand.
Travellin Cats in Jingle Jam

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Amnesia: The Dark Descent
Monsters follow scripted patrols.
Travellin Cats in Jingle Jam
Solo hidden-object game with no opponent
Travellin Cats in Jingle Jam leans a little harder on variance, though the gap is small.

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
