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

Optimization · Systems & Chaos
A narrative-driven horror walk through a Victorian slaughterhouse engine, lighter on systems than its predecessor.

Optimization · Systems & Chaos
A short horror puzzle that tests curiosity about hidden alternative solutions.
Amnesia: A Machine for Pigs leans Optimization (Systems & Chaos); Project Kat: Paper Lily Prologue leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Amnesia: A Machine for Pigs
Walking and lever-pulling demand essentially nothing physical
Project Kat: Paper Lily Prologue
Top-down walking and menu choices only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Amnesia: A Machine for Pigs
Manpigs are scripted set-dressing, rarely a true threat
Project Kat: Paper Lily Prologue
Scripted horror events, nothing models the player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Amnesia: A Machine for Pigs
First-run unknowns are the whole experience; spoilers defuse it
Project Kat: Paper Lily Prologue
Hidden rules and alternate solutions are the hook until discovered
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Amnesia: A Machine for Pigs
Light puzzles and routes are trivially solvable on repeat
Project Kat: Paper Lily Prologue
Puzzles reward experimenting toward fully mappable 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.
