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 · Practiced Mastery
A Cave bullet hell demanding the highest execution ceiling of any mainstream shmup, with a rank system that punishes passivity.

Execution · Practiced Mastery
Nintendo's branching rail shooter where score medals demand perfected routes.
Mushihimesama leans Execution (Practiced Mastery); Star Fox 64 leans Execution (Practiced Mastery).
Mushihimesama leans a little harder on execution, though the gap is small.
Mushihimesama
Ultra Maniac difficulty requires inhuman movement precision
Star Fox 64
Rail-shooter aim, barrel rolls, and boost timing are everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mushihimesama
All bullet patterns are scripted Cave bullet-hell formations
Star Fox 64
Entirely scripted bosses and waves
Mushihimesama leans a little harder on variance, though the gap is small.
Mushihimesama
Rank system alters bullet speed based on play style
Star Fox 64
Fully deterministic once routes are known
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mushihimesama
Shot type selection, rank management, and scoring routes are solvable
Star Fox 64
Medal scores and route branches reward total memorization
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.
