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 · Practiced Mastery
A test of 3D movement control with a deep routing layer underneath.

Execution · Pure Mechanics
A Touhou fan metroidvania where a time-stopping maid weaves through scripted bullet hell.
Super Mario 64 leans Execution (Practiced Mastery); Touhou Luna Nights leans Execution (Pure Mechanics).
Touhou Luna Nights leans a little harder on execution, though the gap is small.
Super Mario 64
Perfect analog inputs trivialise precise jumps, dives and wall-kicks
Touhou Luna Nights
Bullet-pattern dodging and time-stop knife play demand sharp hands
Touhou Luna Nights leans a little harder on reads, though the gap is small.
Super Mario 64
Solo platformer - no adaptive opponent anywhere
Touhou Luna Nights
Boss patterns are fully scripted danmaku
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario 64
Star locations and level layouts are fixed once seen
Touhou Luna Nights
Fixed level layouts, little hidden randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario 64
Star routing and movement tech form a deep solvable layer
Touhou Luna Nights
Learning patterns and time-stop resource management
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.
