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

Variance · Light / Casual
A narrative horror experience testing curiosity more than any skill axis.

Variance · Systems & Chaos
Navigating unseen spaces by sound while rationing the noise that summons danger.
MiSide leans Variance (Light / Casual); Perception leans Variance (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
MiSide
Walking and minigames make light physical demands
Perception
Echolocation taps and walking ask little of the hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
MiSide
Mita is a scripted character, not an adaptive mind
Perception
The Presence triggers on scripted noise thresholds
Perception leans a little harder on variance, though the gap is small.
MiSide
Story surprises are hidden only until experienced
Perception
Blind navigation makes layouts hidden information at first
Perception leans a little harder on optimization, though the gap is small.
MiSide
Linear narrative with simple puzzles to step through
Perception
Managing noise and learning routes converges quickly
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.
