head to head
eXceed 2nd: Vampire REX asks more than Super Mario World, and the gap is execution.

Execution · Pure Mechanics
A vertical bullet-hell shmup testing precise dodging through dense scripted patterns.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
eXceed 2nd: Vampire REX leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
eXceed 2nd: Vampire REX leans clearly harder on execution.
eXceed 2nd: Vampire REX
Dodging dense bullet patterns at speed is the entire test
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.
eXceed 2nd: Vampire REX
Solo - enemies fire fixed scripted patterns, no adaptation
Super Mario World
Scripted Koopas adapt to nothing
eXceed 2nd: Vampire REX leans a little harder on variance, though the gap is small.
eXceed 2nd: Vampire REX
Patterns are deterministic and memorisable, little true randomness
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
eXceed 2nd: Vampire REX leans a little harder on optimization, though the gap is small.
eXceed 2nd: Vampire REX
Polarity routing and scoring systems reward learned play
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.
