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.

Execution · Pure Mechanics
A minimalist rhythm platformer where abstract shapes and hazards pulse in lockstep with the soundtrack.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
140 leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
140 leans a little harder on execution, though the gap is small.
140
Jumps must land on the musical beat precisely
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.
140
No opponent exists
Super Mario World
Scripted Koopas adapt to nothing
Super Mario World leans a little harder on variance, though the gap is small.
140
Fully deterministic rhythm patterns
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
140
Learning each sequence's timing solution
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.
