head to head
Zenzizenzic asks more than Super Mario World, and the gap is execution.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.

Execution · Pure Mechanics
A twin-stick bullet-hell shooter testing reflexes against dense projectile patterns.
Super Mario World leans Execution (Pure Mechanics); Zenzizenzic leans Execution (Pure Mechanics).
Zenzizenzic leans clearly harder on execution.
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Zenzizenzic
Dodging dense bullet patterns at speed is the lead axis
Zenzizenzic leans a little harder on reads, though the gap is small.
Super Mario World
Scripted Koopas adapt to nothing
Zenzizenzic
Enemies fire scripted patterns, no adaptive mind
Zenzizenzic leans clearly harder on variance.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Zenzizenzic
Spawn variety and power-up drops add minor randomness
Zenzizenzic leans a little harder on optimization, though the gap is small.
Super Mario World
Secret exits and route knowledge add a modest solvable layer
Zenzizenzic
Weapon and power-up choices optimize survival potential
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.
