head to head
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 relaxed hidden-object game about spotting cats in detailed scenes.

Variance · Light / Casual
A live-action FMV thriller steered through touchpad choices and gestures.
A Tower Full of Cats leans Optimization (Light / Casual); Erica leans Variance (Light / Casual).
A Tower Full of Cats leans a little harder on execution, though the gap is small.
A Tower Full of Cats
Clicking hidden cats has no timing pressure
Erica
Touch gestures with no skill ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
A Tower Full of Cats
Solo - nothing to predict
Erica
No opponent
Erica leans a little harder on variance, though the gap is small.
A Tower Full of Cats
Cat locations unknown until found, mildly randomized feel
Erica
Branch outcomes hidden on first viewing
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
A Tower Full of Cats
Systematic scanning speeds completion but trivial
Erica
Mapping choice branches across replays
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.
