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

Execution · Pure Mechanics
A horizontal shoot-em-up built around time manipulation and bullet-hell dodging.

Execution · Pure Mechanics
A brutal minimalist platformer where flipping gravity replaces jumping.
Sine Mora leans Execution (Pure Mechanics); VVVVVV 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.
Sine Mora
precise bullet-hell dodging is the whole test
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.
Sine Mora
scripted enemy patterns, not adaptive
VVVVVV
No opponent
Sine Mora leans a little harder on variance, though the gap is small.
Sine Mora
minimal randomness in patterns
VVVVVV
Every hazard is fixed and visible
Sine Mora leans a little harder on optimization, though the gap is small.
Sine Mora
time-manipulation and route memorization
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.
