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 · Practiced Mastery
A lovingly pixelled aerial adventure where Otus carries gunner friends through floating islands.

Optimization · Pure Optimization
Body-altering puzzle platforming where each obstacle has an intended grim solution.
Owlboy leans Optimization (Practiced Mastery); The Missing: J.J. Macfield and the Island of Memories leans Optimization (Pure Optimization).
Owlboy leans a little harder on execution, though the gap is small.
Owlboy
Flying and gunner-swapping in light combat
The Missing: J.J. Macfield and the Island of Memories
Platforming is deliberately loose and forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Owlboy
Scripted pirates and bosses
The Missing: J.J. Macfield and the Island of Memories
No adaptive opposition exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Owlboy
Hand-crafted, deterministic world
The Missing: J.J. Macfield and the Island of Memories
Hand-crafted puzzles, fixed every run
The Missing: J.J. Macfield and the Island of Memories leans a little harder on optimization, though the gap is small.
Owlboy
Boss patterns and secrets are learnable
The Missing: J.J. Macfield and the Island of Memories
Using self-mutilation mechanics correctly per puzzle 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.
