head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
Experimenting with whimsical screens until their hidden interaction logic clicks.

Optimization · Pure Optimization
Cross-referencing hidden clues into deductions about a fixed murder mystery.
Samorost 2 leans Optimization (Pure Optimization); Tangle Tower leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Samorost 2
Pointing and clicking has no dexterity component
Tangle Tower
Pointing and clicking, nothing physical
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Samorost 2
No opponent of any kind exists
Tangle Tower
Suspects are written characters, not adaptive minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Samorost 2
Surreal puzzle logic is hidden until experimented with
Tangle Tower
The murder's facts are hidden until clues surface
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Samorost 2
Each screen is a small solvable interaction puzzle
Tangle Tower
Cross-referencing clues into deductions is the test
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.
