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.

Optimization · Pure Optimization
Hand-painted puzzle adventure where light turns monsters into furniture.

Optimization · Pure Optimization
A wordless robot puzzle adventure where every environmental obstacle has exactly one elegant solution.
Creaks leans Optimization (Pure Optimization); Machinarium leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Creaks
light timing on monster movement
Machinarium
A handful of mini-games require basic timing and clicking precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Creaks
no adaptive opponent
Machinarium
Solo robot puzzle game with no opponent
Machinarium leans a little harder on variance, though the gap is small.
Creaks
puzzles fully visible once entered
Machinarium
Arcade mini-games add minor randomness but are skipable
Machinarium leans a little harder on optimization, though the gap is small.
Creaks
each room is a solvable logic puzzle
Machinarium
Environmental logic puzzles are tightly designed closed-world problems
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.
