BIT.TRIP RUNNERVVVVVV
Axis by axis
Execution9 vs 9
Even - both lean on execution about the same.
Reads0 vs 0
Even - both lean on reads about the same.
Variance1 vs 0
BIT.TRIP RUNNER leans harder on variance: Fully deterministic level patterns
Optimization3 vs 3
Even - both lean on optimization about the same.
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
