head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
A vertical-scrolling bullet-hell shoot-em-up.

Execution · Pure Mechanics
A boss-rush action game that is nothing but execution tests against scripted duelists.
Bullet Soul leans Execution (Pure Mechanics); Furi 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.
Bullet Soul
dense bullet dodging demands precise reflexes
Furi
Parry timing, bullet dodging, and duel precision
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
Furi
Bosses are scripted patterns, however adversarial they feel
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
Furi
Fixed boss sequences
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bullet Soul
pattern memorization for scoring runs
Furi
Learning each boss's phases converges to mastery
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.
