Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
A school murder mystery where class trials test players' ability to assemble evidence into the correct counter-argument.

Optimization · Pure Optimization
Hunting hidden objects and solving puzzles through a fixed mystery narrative.

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

Class trial rhythm sections add minor timing layer
Mystery Case Files: Fate's Carnival
Clicking objects has no twitch demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Danganronpa: Trigger Happy Havoc

Mystery Case Files: Fate's Carnival

Mystery Case Files: Fate's Carnival
Hidden objects are fixed, just unfound until searched
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Mystery Case Files: Fate's Carnival
Solving puzzles and finding items is the entire loop
