head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Systems & Chaos
A horror adventure testing careful flag-tracking to dodge scripted bad endings.

Optimization · Systems & Chaos
Guided detective clue-hunting with hidden answers and minimal challenge.
Corpse Party: Blood Drive leans Optimization (Systems & Chaos); Murdered: Soul Suspect leans Optimization (Systems & Chaos).
Corpse Party: Blood Drive leans a little harder on execution, though the gap is small.
Corpse Party: Blood Drive
Light chase-evasion sequences barely tax the hands
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: Blood Drive
Ghosts follow scripted horror triggers
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: Blood Drive
Wrong-end triggers are hidden until discovered
Murdered: Soul Suspect
Clues and case answers are hidden until found
Corpse Party: Blood Drive leans a little harder on optimization, though the gap is small.
Corpse Party: Blood Drive
Mapping flag conditions for true endings is the game
Murdered: Soul Suspect
Deduction sequences are guided puzzles with known answers
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.
