head to head
Neither is simply harder - they are hard in different places. Moorhuhn 2: Die Jagd Geht Weiter demands more variance; Super Mario World demands more optimization.

Execution · Pure Mechanics
A lighthearted shooting-gallery game about reflexively gunning down randomly appearing chickens.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
Moorhuhn 2: Die Jagd Geht Weiter leans Execution (Pure Mechanics); Super Mario World leans Execution (Pure Mechanics).
Super Mario World leans a little harder on execution, though the gap is small.
Moorhuhn 2: Die Jagd Geht Weiter
precise aiming and shooting reflexes
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.
Moorhuhn 2: Die Jagd Geht Weiter
no opponent, solo shooting gallery
Super Mario World
Scripted Koopas adapt to nothing
Moorhuhn 2: Die Jagd Geht Weiter leans clearly harder on variance.
Moorhuhn 2: Die Jagd Geht Weiter
chicken spawn pattern randomness
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Super Mario World leans clearly harder on optimization.
Moorhuhn 2: Die Jagd Geht Weiter
minimal, mostly reflexive scoring
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.
