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 scripted RPG-Maker horror testing puzzle-solving and route knowledge.

Optimization · Pure Optimization
A psychological horror RPG where a shut-in's dream world slowly cracks around a buried truth.
Mad Father 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.
Mad Father
Light chase sequences barely test the hands
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.
Mad Father
Scripted horror events, nothing adapts
Omori
Scripted encounters throughout
Mad Father leans a little harder on variance, though the gap is small.
Mad Father
Scares and puzzle items are unknown on first playthrough
Omori
Minor drop and emotion randomness
Omori leans a little harder on optimization, though the gap is small.
Mad Father
Item puzzles and ending routes are fully mappable
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.
