B.C.'s Quest for TiresVVVVVV
Axis by axis
Execution8 vs 9
VVVVVV leans harder on execution: Pixel-perfect gravity flips through spike gauntlets
Reads0 vs 0
Even - both lean on reads about the same.
Variance1 vs 0
B.C.'s Quest for Tires leans harder on variance: Fixed obstacle sequences, almost no randomness
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.
