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 · Practiced Mastery
A puzzle-leaning platformer testing perspective-flip problem solving more than reflexes.
Planet of Lana leans Optimization (Practiced Mastery); Super Paper Mario leans Optimization (Practiced Mastery).
Super Paper Mario leans a little harder on execution, though the gap is small.
Planet of Lana
Gentle platforming and chase sequences
Super Paper Mario
Light platforming demands, well below mainline Mario
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
Super Paper Mario
Enemies follow simple fixed patterns, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Planet of Lana
Fully authored puzzles
Super Paper Mario
Dimension-flip secrets are scripted-but-unknown until found
Super Paper Mario leans a little harder on optimization, though the gap is small.
Planet of Lana
Companion-command puzzles have single solutions
Super Paper Mario
Solving levels via the 2D/3D flip mechanic is the core test
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.
