head to head
Super Hexagon asks more than Donkey Kong Junior, and the gap is execution.

Execution · Pure Mechanics
An early arcade climber demanding tight, repeatable jump execution.

Execution · Pure Mechanics
Terry Cavanagh's minimalist reflex gauntlet of rotating walls measured in seconds survived.
Donkey Kong Junior leans Execution (Pure Mechanics); Super Hexagon leans Execution (Pure Mechanics).
Super Hexagon leans clearly harder on execution.
Donkey Kong Junior
precise vine-climbing and jump timing
Super Hexagon
Sub-second reactions at extreme speed, pure reflex ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong Junior
enemies follow fixed patrol patterns
Super Hexagon
No opponent, only walls
Super Hexagon leans a little harder on variance, though the gap is small.
Donkey Kong Junior
minor enemy timing variance
Super Hexagon
Pattern order randomized from a known set
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong Junior
minimal route memorization needed
Super Hexagon
Pattern vocabulary is small, reaction is everything
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.
