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.

Optimization · Pure Optimization
Gorgeous co-op puzzle-platforming where the cleverest contraption wins, not the fastest fingers.

Optimization · Practiced Mastery
A gentle physics puzzle-platformer starring a creature made of unraveling yarn.
Trine 2 leans Optimization (Pure Optimization); Unravel leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Trine 2
Rope swings and box physics demand moderate dexterity
Unravel
Gentle platforming and yarn-swing timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Trine 2
Static puzzles, no adaptive opposition
Unravel
No opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Trine 2
Everything is visible and deterministic
Unravel
Everything is visible and fixed
Trine 2 leans a little harder on optimization, though the gap is small.
Trine 2
Hero-swap puzzle solving is the central test
Unravel
Physics puzzles with discoverable intended solutions
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.
