head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Practiced Mastery
Tests puzzle solving by picking the right blob transformation for each fixed obstacle.

Optimization · Practiced Mastery
A puzzle-leaning platformer testing perspective-flip problem solving more than reflexes.
A Boy and His Blob leans Optimization (Practiced Mastery); Super Paper Mario leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
A Boy and His Blob
Gentle platforming with forgiving timing
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.
A Boy and His Blob
Solo puzzle world - nothing adapts
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.
A Boy and His Blob
Levels are fixed; secrets known after one find
Super Paper Mario
Dimension-flip secrets are scripted-but-unknown until found
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
A Boy and His Blob
Choosing the right bean transformation per obstacle is the puzzle
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.
