Axis by axis
Execution10 vs 9
Super Hexagon leans harder on execution: Sub-second reactions at extreme speed, pure reflex ceiling
Reads0 vs 0
Even - both lean on reads about the same.
Variance2 vs 0
Super Hexagon leans harder on variance: Pattern order randomized from a known set
Optimization2 vs 3
VVVVVV leans harder on optimization: Routes are short and obvious; execution is everything
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
