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 · Systems & Chaos
A hidden-object game testing systematic visual search for hidden cats.

Optimization · Pure Optimization
A psychological horror RPG where a shut-in's dream world slowly cracks around a buried truth.
100 Istanbul Cats leans Optimization (Systems & Chaos); 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.
100 Istanbul Cats
Scanning and clicking demands no twitch
Omori
Turn-based menus, no dexterity needed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
100 Istanbul Cats
Solo hidden-object game, no opponent
Omori
Scripted encounters throughout
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
100 Istanbul Cats
Cat placement hidden until found
Omori
Minor drop and emotion randomness
Omori leans a little harder on optimization, though the gap is small.
100 Istanbul Cats
Systematic scanning of the scene finds every cat
Omori
Emotion triangle and follow-ups are easily solvable
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.
