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

A hidden-object detective adventure testing fixed-puzzle deduction.

Optimization · Pure Optimization
A psychological horror RPG where a shut-in's dream world slowly cracks around a buried truth.
Enigmatis 3: The Shadow of Karkhala leans Optimization (Pure Optimization); Omori 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.

Point-and-click needs no motor precision
Omori
Turn-based menus, no dexterity needed
Enigmatis 3: The Shadow of Karkhala leans a little harder on reads, though the gap is small.

Solo detective story; no adaptive opponent
Omori

Hidden objects but fixed per-scene solutions
Omori

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
