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

Optimization · Pure Optimization
A psychological horror RPG where a shut-in's dream world slowly cracks around a buried truth.

Optimization · Systems & Chaos
A visual novel first and a light tactics game second, heavy on story.
Omori leans Optimization (Pure Optimization); Utawarerumono: Mask of Deception leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Omori
Turn-based menus, no dexterity needed
Utawarerumono: Mask of Deception
Optional timing presses on attacks
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Omori
Scripted encounters throughout
Utawarerumono: Mask of Deception
Enemy AI is scripted and predictable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Omori
Minor drop and emotion randomness
Utawarerumono: Mask of Deception
Light combat RNG in a mostly fixed story
Omori leans a little harder on optimization, though the gap is small.
Omori
Emotion triangle and follow-ups are easily solvable
Utawarerumono: Mask of Deception
Easy SRPG battles solved with basic positioning
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.
