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
Infamous climbing game where one slip of the hammer undoes hours of progress.

Execution · Pure Mechanics
A precision marble-rolling platformer focused on time trials.
Getting Over It with Bennett Foddy leans Execution (Pure Mechanics); Marble It Up! Ultra 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.
Getting Over It with Bennett Foddy
Every inch climbed is precise hammer micro-control
Marble It Up! Ultra
precise marble physics control is everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Getting Over It with Bennett Foddy
The mountain never adapts
Marble It Up! Ultra
no opponent, solo time-trial skill
Marble It Up! Ultra leans a little harder on variance, though the gap is small.
Getting Over It with Bennett Foddy
Fully deterministic physics and terrain
Marble It Up! Ultra
deterministic physics, minimal randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Getting Over It with Bennett Foddy
Route knowledge helps but cannot replace hands
Marble It Up! Ultra
route optimization for best times
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.
