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 · Pure Optimization
First-person puzzle adventure unraveling a Lovecraft-tinged island mystery.

Optimization · Pure Optimization
Noir stealth puzzler about rewiring buildings so guards defeat themselves.
Call of the Sea leans Optimization (Pure Optimization); Gunpoint leans Optimization (Pure Optimization).
Gunpoint leans a little harder on execution, though the gap is small.
Call of the Sea
Walking and clicking, no dexterity test
Gunpoint
Jump timing matters occasionally, lightly
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of the Sea
No opponent of any kind
Gunpoint
Guards patrol on fixed scripts
Call of the Sea leans a little harder on variance, though the gap is small.
Call of the Sea
Hidden solutions surprise only once
Gunpoint
Levels fully visible and deterministic
Call of the Sea leans a little harder on optimization, though the gap is small.
Call of the Sea
Deducing fixed puzzle logic is the whole game
Gunpoint
Crosslink rewiring puzzles have clean optimal solutions
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.
