head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Pure Mechanics
A brutally precise platformer about dying thousands of times.

Execution · Pure Mechanics
A brutal minimalist platformer where flipping gravity replaces jumping.
Super Meat Boy leans Execution (Pure Mechanics); VVVVVV leans Execution (Pure Mechanics).
Super Meat Boy leans a little harder on execution, though the gap is small.
Super Meat Boy
Pure twitch platforming, frame-perfect jumps
VVVVVV
Pixel-perfect gravity flips through spike gauntlets
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Meat Boy
No adaptive opponent
VVVVVV
No opponent
Super Meat Boy leans a little harder on variance, though the gap is small.
Super Meat Boy
Fully deterministic levels
VVVVVV
Every hazard is fixed and visible
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Meat Boy
Route memorization optimizes times
VVVVVV
Routes are short and obvious; execution 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.
