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

Execution · Practiced Mastery
A boss-rush bullet hell testing dodge execution against learnable scripted patterns.

Execution · Practiced Mastery
A rail shooter testing reflex execution against fully memorisable enemy waves.
Itta leans Execution (Practiced Mastery); Star Fox leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Itta
Bullet-hell boss patterns demand precise dodging and aim
Star Fox
Dodging, shooting and barrel rolls on rails demand reflexes
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Itta
Bosses fire scripted patterns, never adapting
Star Fox
Every enemy wave is a fixed scripted pattern
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Itta
Encounters are fixed once seen
Star Fox
Routes and spawns are deterministic per path
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Itta
Learning each boss's pattern is the path to victory
Star Fox
Memorising wave patterns and route choices for score
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.
