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
A vertical-scrolling bullet-hell shoot-em-up.

Execution · Practiced Mastery
A one-hit boss-rush where solving each titan still demands perfect execution.
Bullet Soul leans Execution (Pure Mechanics); Titan Souls leans Execution (Practiced Mastery).
Bullet Soul leans a little harder on execution, though the gap is small.
Bullet Soul
dense bullet dodging demands precise reflexes
Titan Souls
One arrow, one hit point; every shot must be perfect
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
Titan Souls
Bosses are scripted patterns, not adaptive minds
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
Titan Souls
Unknown boss gimmicks only on first attempts
Titan Souls leans a little harder on optimization, though the gap is small.
Bullet Soul
pattern memorization for scoring runs
Titan Souls
Each titan has a solvable weak-point strategy
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.
