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 dark psychological narrative game about twin sisters, a drowned body, and wartime Italy, told through photography.

Optimization · Pure Optimization
A psychological horror RPG where a shut-in's dream world slowly cracks around a buried truth.
Martha Is Dead 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.
Martha Is Dead
Walking and photography mechanics demand nothing physical
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.
Martha Is Dead
No opponents; the story unfolds regardless of play
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.
Martha Is Dead
Narrative twists are the only meaningful unknowns
Omori
Minor drop and emotion randomness
Omori leans a little harder on optimization, though the gap is small.
Martha Is Dead
Darkroom photography and choices are light, learnable systems
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.
