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.

Variance · Systems & Chaos
A short horror walk that tests little beyond finding fixed clues under scripted scares.

Optimization · Systems & Chaos
Surveillance thriller where you decide which citizens' secrets to report to the state.
Don't Knock Twice leans Variance (Systems & Chaos); Orwell: Keeping an Eye on You leans Optimization (Systems & Chaos).
Don't Knock Twice leans a little harder on execution, though the gap is small.
Don't Knock Twice
Walking and grabbing objects - no dexterity test
Orwell: Keeping an Eye on You
Reading and clicking documents only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Don't Knock Twice
The witch follows scripted triggers, not an adapting mind
Orwell: Keeping an Eye on You
Story characters are scripted, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Don't Knock Twice
Scares and clue placement are unknown until experienced
Orwell: Keeping an Eye on You
Truth is hidden until you uncover contradicting datachunks
Orwell: Keeping an Eye on You leans a little harder on optimization, though the gap is small.
Don't Knock Twice
Puzzle solutions and routes are fixed once learned
Orwell: Keeping an Eye on You
Choosing which evidence to upload steers fixed outcomes
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.
