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

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

Variance · Light / Casual
A painterly hidden-object game testing visual scanning patience.
MiSide leans Variance (Light / Casual); Under Leaves leans Variance (Light / Casual).
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
Under Leaves
Tapping spotted objects requires nothing physical
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
Under Leaves
No opponent exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
MiSide
Story surprises are hidden only until experienced
Under Leaves
Object locations are hidden until found - that is the game
MiSide leans a little harder on optimization, though the gap is small.
MiSide
Linear narrative with simple puzzles to step through
Under Leaves
Systematic scanning is the only technique
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.
