head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Pure Mechanics
Floaty one-button momentum control in arcade altitude duels.

Execution · Pure Mechanics
A timed shooting gallery testing aim and speed against flying chickens.
Balloon Fight leans Execution (Pure Mechanics); Die Original Moorhuhn Jagd leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Balloon Fight
Flap-physics altitude duels demand precise momentum control
Die Original Moorhuhn Jagd
Fast accurate aiming at flying chickens is everything
Balloon Fight leans a little harder on reads, though the gap is small.
Balloon Fight
A couch rival adds light prediction; birds don't adapt
Die Original Moorhuhn Jagd
Chickens follow scripted flight, not adapting
Die Original Moorhuhn Jagd leans a little harder on variance, though the gap is small.
Balloon Fight
Enemy drift and lightning add arcade randomness
Die Original Moorhuhn Jagd
Spawn timing and paths add some unpredictability
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Balloon Fight
Spawn patterns and safe positions are quickly mapped
Die Original Moorhuhn Jagd
Prioritizing targets for max score matters slightly
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.
