head to head
Super Mario World asks more than No Thing, and the gap is optimization.

Execution · Pure Mechanics
A surreal auto-runner testing nothing but sustained split-second turn timing.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
No Thing leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Super Mario World leans a little harder on execution, though the gap is small.
No Thing
Split-second turn timing at speed is the entire game
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
No Thing
No opponent, only the track
Super Mario World
Scripted Koopas adapt to nothing
Super Mario World leans a little harder on variance, though the gap is small.
No Thing
Courses are fixed and memorisable
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Super Mario World leans clearly harder on optimization.
No Thing
Memorising turn sequences helps but reflexes still rule
Super Mario World
Secret exits and route knowledge add a modest solvable layer
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.
