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

Execution · Practiced Mastery
A precision metroidvania about learning fixed boss patterns and tight platforming.

Execution · Pure Mechanics
A Touhou fan metroidvania where a time-stopping maid weaves through scripted bullet hell.
Hollow Knight 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.
Hollow Knight
Precise platforming and pogo timing dominate hard content.
Touhou Luna Nights
Bullet-pattern dodging and time-stop knife play demand sharp hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hollow Knight
Bosses run scripted attack pools; not adaptive.
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.
Hollow Knight
Negligible; world layout is fixed.
Touhou Luna Nights
Fixed level layouts, little hidden randomness
Hollow Knight leans a little harder on optimization, though the gap is small.
Hollow Knight
Charm builds and boss routes are 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.
