head to head
Super Hexagon asks more than osu!, and the gap is variance.

Execution · Pure Mechanics
Rhythm game where clicking circles to the beat becomes an athletic discipline.

Execution · Pure Mechanics
Terry Cavanagh's minimalist reflex gauntlet of rotating walls measured in seconds survived.
osu! leans Execution (Pure Mechanics); Super Hexagon 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.
osu!
Pixel-perfect cursor aim and tapping at extreme speeds
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.
osu!
No opponent interaction in scoring
Super Hexagon
No opponent, only walls
Super Hexagon leans clearly harder on variance.
osu!
Beatmaps are fully deterministic
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.
osu!
Mod choices and map selection for ranking
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.
