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 · Practiced Mastery
Painterly cinematic puzzle platformer about a girl and her cat-like companion.

Optimization · Pure Optimization
Reasoning through fixed adventure-logic puzzles inside a sci-fi story.
Planet of Lana leans Optimization (Practiced Mastery); The Fall leans Optimization (Pure Optimization).
Planet of Lana leans a little harder on execution, though the gap is small.
Planet of Lana
Gentle platforming and chase sequences
The Fall
Light combat and platforming pose little physical test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Planet of Lana
Machines follow scripted patterns
The Fall
Story AI characters are fully scripted
The Fall leans a little harder on variance, though the gap is small.
Planet of Lana
Fully authored puzzles
The Fall
Puzzle solutions are hidden until reasoned out
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Planet of Lana
Companion-command puzzles have single solutions
The Fall
Adventure-logic puzzles each have one intended answer
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.
