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.

Optimization · Pure Optimization
Hunting each level's optimal slingshot solution under mild physics noise.

Optimization · Practiced Mastery
A co-op yarn puzzle-platformer where two tethered characters solve levels together.
Angry Birds Star Wars leans Optimization (Pure Optimization); Unravel Two leans Optimization (Practiced Mastery).
Unravel Two leans a little harder on execution, though the gap is small.
Angry Birds Star Wars
Slingshot aim needs only mild touch precision
Unravel Two
Light platforming plus two-character swing coordination
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Angry Birds Star Wars
Pigs sit motionless awaiting demolition
Unravel Two
No adaptive opposition, co-op only
Angry Birds Star Wars leans a little harder on variance, though the gap is small.
Angry Birds Star Wars
Physics tumbles add slight outcome noise per shot
Unravel Two
Fixed levels, fully visible
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Angry Birds Star Wars
Finding each level's three-star shot solution is the game
Unravel Two
Puzzles solved by routing two yarn characters together
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.
