A horror visual novel testing careful choice-mapping to avoid hidden bad endings.

Corpse Party: Book of Shadows leans Optimization (Systems & Chaos); Murdered: Soul Suspect leans Optimization (Systems & Chaos).
Murdered: Soul Suspect leans a little harder on execution, though the gap is small.
Corpse Party: Book of Shadows
Visual-novel navigation needs only reading
Murdered: Soul Suspect
Walking and clue-clicking; demon stealth is trivial
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Corpse Party: Book of Shadows
No adaptive opponent in the cursed school
Murdered: Soul Suspect
Demons follow simple fixed patrols
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Corpse Party: Book of Shadows
Wrong-end triggers are hidden until discovered
Murdered: Soul Suspect
Clues and case answers are hidden until found
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Corpse Party: Book of Shadows
Mapping flags and choices to endings is the only system
Murdered: Soul Suspect
Deduction sequences are guided puzzles with known answers
