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

Execution · Practiced Mastery
A test of 3D movement control with a deep routing layer underneath.
Clustertruck leans Execution (Pure Mechanics); Super Mario 64 leans Execution (Practiced Mastery).
Clustertruck leans a little harder on execution, though the gap is small.
Clustertruck
Frame-tight jumps across moving trucks
Super Mario 64
Perfect analog inputs trivialise precise jumps, dives and wall-kicks
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 64
Solo platformer - no adaptive opponent anywhere
Clustertruck leans a little harder on variance, though the gap is small.
Clustertruck
Physics chaos makes truck piles unpredictable
Super Mario 64
Star locations and level layouts are fixed once seen
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Clustertruck
Route lines and ability use for speedruns
Super Mario 64
Star routing and movement tech form a deep solvable layer
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.
