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 precision metroidvania about learning fixed boss patterns and tight platforming.

Execution · Practiced Mastery
GBA platformer where Wario smashes through puzzle levels and races escape timers for treasure.
Hollow Knight leans Execution (Practiced Mastery); Wario Land 4 leans Execution (Practiced Mastery).
Hollow Knight leans a little harder on execution, though the gap is small.
Hollow Knight
Precise platforming and pogo timing dominate hard content.
Wario Land 4
Frantic escape sequences demand tight platforming under timers
Hollow Knight leans a little harder on reads, though the gap is small.
Hollow Knight
Bosses run scripted attack pools; not adaptive.
Wario Land 4
Fixed scripted levels with no adaptive opposition
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hollow Knight
Negligible; world layout is fixed.
Wario Land 4
Layouts fixed; only first-run secret discovery
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Hollow Knight
Charm builds and boss routes are fully learnable.
Wario Land 4
Treasure routing and frog-switch timing reward planning
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.
