head to head
Neither is simply harder - they are hard in different places. Hello Neighbor demands more optimization; In Silence demands more reads.

Optimization · Systems & Chaos
Stealth puzzle horror about breaking into a suburban neighbor's secret-filled house.

Variance · Bluff & Deduction
An asymmetric multiplayer horror game about staying silent while a human-controlled monster hunts by sound.
Hello Neighbor leans Optimization (Systems & Chaos); In Silence leans Variance (Bluff & Deduction).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Hello Neighbor
Light sneaking and parkour
In Silence
Sneaking and quiet movement need light control, not twitch
In Silence leans clearly harder on reads.
Hello Neighbor
Marketed adaptive AI is mostly mappable in practice
In Silence
The monster is a human player reacting to sound
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hello Neighbor
Neighbor patrols and traps feel erratic
In Silence
Hidden monster position and noise create tension
Hello Neighbor leans clearly harder on optimization.
Hello Neighbor
Puzzle solutions and route knowledge solve each act
In Silence
Sound management and objective routing are learnable
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.
