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

Execution · Pure Mechanics
A top-down shmup testing dodging and aiming against memorizable bullet patterns.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Alltynex Second leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Alltynex Second leans clearly harder on execution.
Alltynex Second
Bullet-hell dodging and aiming are the whole skill
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
Alltynex Second leans a little harder on reads, though the gap is small.
Alltynex Second
Bosses are fixed patterns, not adaptive
Super Mario World
Scripted Koopas adapt to nothing
Alltynex Second leans a little harder on variance, though the gap is small.
Alltynex Second
Patterns memorizable, little true randomness
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Alltynex Second leans a little harder on optimization, though the gap is small.
Alltynex Second
Learning safe routes and sword timing optimizes survival
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.
