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
Slapstick physics puzzler about hauling a wobbly ragdoll through dreamscapes.

Optimization · Practiced Mastery
Painterly cinematic puzzle platformer about a girl and her cat-like companion.
Human: Fall Flat leans Optimization (Practiced Mastery); Planet of Lana leans Optimization (Practiced Mastery).
Human: Fall Flat leans a little harder on execution, though the gap is small.
Human: Fall Flat
Wrestling floppy physics limbs is the joke
Planet of Lana
Gentle platforming and chase sequences
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Human: Fall Flat
No adversary, only wobbly geometry
Planet of Lana
Machines follow scripted patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Human: Fall Flat
Physics jank adds slapstick unpredictability
Planet of Lana
Fully authored puzzles
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Human: Fall Flat
Puzzle solutions and shortcut discovery
Planet of Lana
Companion-command puzzles have single 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.
