head to head
Shikhondo: Soul Eater asks more than Super Mario World, and the gap is execution.

Execution · Pure Mechanics
A bullet-hell shooter testing precise dodging through scripted Korean-mythology patterns.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Shikhondo: Soul Eater leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Shikhondo: Soul Eater leans clearly harder on execution.
Shikhondo: Soul Eater
Weaving through dense bullet patterns is the entire game
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Shikhondo: Soul Eater leans a little harder on reads, though the gap is small.
Shikhondo: Soul Eater
Bosses fire scripted patterns, not adaptation
Super Mario World
Scripted Koopas adapt to nothing
Shikhondo: Soul Eater leans clearly harder on variance.
Shikhondo: Soul Eater
Some spawn and item-timing randomness
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Shikhondo: Soul Eater leans a little harder on optimization, though the gap is small.
Shikhondo: Soul Eater
Pattern memorization and scoring routes reward study
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.
