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
A gentle hidden-object hunt through painted insect scenes with light puzzles.

Optimization · Pure Optimization
A supernatural teen drama where dialogue timing shapes relationships against a fixed mystery structure.
Morphopolis leans Optimization (Systems & Chaos); Oxenfree 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.
Morphopolis
Clicking painted scenes needs no dexterity
Oxenfree
Radio tuning and walking demand no physical skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Morphopolis
No opponent of any kind
Oxenfree
Supernatural narrative with scripted ghost behaviour
Morphopolis leans a little harder on variance, though the gap is small.
Morphopolis
Hidden objects are scripted-but-unknown until spotted
Oxenfree
Dialogue timing creates minor branching uncertainty
Oxenfree leans a little harder on optimization, though the gap is small.
Morphopolis
Simple puzzle chains have single fixed answers
Oxenfree
Relationship and dialogue choices converge toward fixed endings
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.
