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 · Systems & Chaos
Scanning a dinosaur park illustration for hidden cats, nothing more.

Variance · Light / Casual
A narrative horror experience testing curiosity more than any skill axis.
100 Dino Cats leans Variance (Systems & Chaos); MiSide 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.
100 Dino Cats
Clicking spotted cats takes no skill
MiSide
Walking and minigames make light physical demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
100 Dino Cats
A static scene never adapts
MiSide
Mita is a scripted character, not an adaptive mind
100 Dino Cats leans a little harder on variance, though the gap is small.
100 Dino Cats
Hidden cat placements are the only unknown
MiSide
Story surprises are hidden only until experienced
MiSide leans a little harder on optimization, though the gap is small.
100 Dino Cats
Grid-scanning the artwork is the lone technique
MiSide
Linear narrative with simple puzzles to step through
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.
