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

Execution · Pure Mechanics
A light-gun rail shooter testing aim and reaction against scripted enemies.

Execution · Pure Mechanics
A punishing retro platformer where precise jump timing is everything.
Confidential Mission leans Execution (Pure Mechanics); Hudson's Adventure Island leans Execution (Pure Mechanics).
Confidential Mission leans a little harder on execution, though the gap is small.
Confidential Mission
Light-gun aim and fast reactions are the whole game
Hudson's Adventure Island
tight platform jumps, brutal timing windows
Confidential Mission leans a little harder on reads, though the gap is small.
Confidential Mission
Enemies pop on scripts, not adaptive prediction
Hudson's Adventure Island
fixed enemy patterns, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Confidential Mission
Enemy appearance timing adds minor randomness
Hudson's Adventure Island
fruit/egg drops randomized
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Confidential Mission
Memorizing enemy positions rewards repeated play
Hudson's Adventure Island
level route and skateboard memorization
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.
