head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
The 1981 arcade classic of climbing girders and dodging barrels.

Execution · Pure Mechanics
A Touhou fan metroidvania where a time-stopping maid weaves through scripted bullet hell.
Donkey Kong leans Execution (Practiced Mastery); Touhou Luna Nights 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.
Donkey Kong
Frame-tight jumps over barrels under arcade pressure
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.
Donkey Kong
Fixed arcade patterns, nothing adapts
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.
Donkey Kong
Barrel bounces add slight unpredictability
Touhou Luna Nights
Fixed level layouts, little hidden randomness
Donkey Kong leans a little harder on optimization, though the gap is small.
Donkey Kong
Stage patterns and score routes fully learnable
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.
