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.

Execution · Practiced Mastery
A bite-sized 3D Mario that compresses Galaxy-style level design into linear handheld courses.
Human: Fall Flat leans Optimization (Practiced Mastery); Super Mario 3D Land leans Execution (Practiced Mastery).
Super Mario 3D Land leans a little harder on execution, though the gap is small.
Human: Fall Flat
Wrestling floppy physics limbs is the joke
Super Mario 3D Land
3D jumps and special-world remixes need clean control
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
Super Mario 3D Land
Scripted enemies and bosses only
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
Super Mario 3D Land
Star coin locations hidden on first pass
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
Super Mario 3D Land
Star coin collection and power-up management are solvable
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.
