head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
A light-gun arcade shooter testing fast, accurate aim against waves of hazards.

Execution · Pure Mechanics
A punishing retro platformer where precise jump timing is everything.
Gumshoe leans Execution (Pure Mechanics); Hudson's Adventure Island 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.
Gumshoe
Light-gun aiming and fast reflexes decide survival
Hudson's Adventure Island
tight platform jumps, brutal timing windows
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gumshoe
Enemies follow fixed arcade patterns, no adaptation
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.
Gumshoe
Diamond placement and enemy spawns add minor chaos
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.
Gumshoe
Learning level layouts gives a modest edge
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.
