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
Push-forward arena FPS where movement and aim are the whole game.

Execution · Pure Mechanics
A marble-rolling platformer testing precise physics control for record times.
DOOM (2016) leans Execution (Pure Mechanics); Marble It Up! leans Execution (Pure Mechanics).
Marble It Up! leans a little harder on execution, though the gap is small.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
Marble It Up!
Frame-perfect marble control and boosting decide every run
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Marble It Up!
Solo time-trials - no opponent to predict
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Minimal encounter randomness.
Marble It Up!
Physics are deterministic, nothing random
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Rune and weapon mod picks meaningful.
Marble It Up!
Finding optimal lines for record times rewards mastery
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.
