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
First-person physics platformer about leaping across a convoy of crashing trucks.

Execution · Pure Mechanics
Player-made platforming gauntlets where precision execution meets unseen level design.
Clustertruck leans Execution (Pure Mechanics); Super Mario Maker 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.
Clustertruck
Frame-tight jumps across moving trucks
Super Mario Maker
Community kaizo levels push platforming precision to extremes
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Clustertruck
No opponent
Super Mario Maker
Levels are static once built; nothing adapts
Super Mario Maker leans a little harder on variance, though the gap is small.
Clustertruck
Physics chaos makes truck piles unpredictable
Super Mario Maker
Unknown user levels are hidden information until attempted
Clustertruck leans a little harder on optimization, though the gap is small.
Clustertruck
Route lines and ability use for speedruns
Super Mario Maker
Mastering tool tech and level conventions is learnable
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.
