Execution · Practiced Mastery
A precision metroidvania about learning fixed boss patterns and tight platforming.
Bullet Soul leans Execution (Pure Mechanics); Hollow Knight leans Execution (Practiced Mastery).

Axis by axis
Execution9 vs 8
Bullet Soul leans a little harder on execution, though the gap is small.
Bullet Soul
dense bullet dodging demands precise reflexes
Hollow Knight
Precise platforming and pogo timing dominate hard content.
Reads1 vs 1
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bullet Soul
bullet patterns fixed, not adaptive
Hollow Knight
Bosses run scripted attack pools; not adaptive.
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bullet Soul
minimal pattern randomness
Hollow Knight
Negligible; world layout is fixed.
Optimization5 vs 6
Hollow Knight leans a little harder on optimization, though the gap is small.
Bullet Soul
pattern memorization for scoring runs
Hollow Knight
Charm builds and boss routes are fully 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.
