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

Optimization · Systems & Chaos
Gothic adventure testing methodical puzzle solving through a fixed mystery plot.

Optimization · Pure Optimization
Experimenting with whimsical screens until their hidden interaction logic clicks.
Black Mirror III: Final Fear leans Optimization (Systems & Chaos); Samorost 2 leans Optimization (Pure Optimization).

Pointing and clicking carries no physical ceiling
Samorost 2
Pointing and clicking has no dexterity component
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Black Mirror III: Final Fear
Inventory puzzles have single fixed solutions
Samorost 2
Each screen is a small solvable interaction puzzle
