head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Practiced Mastery
A precision metroidvania about learning fixed boss patterns and tight platforming.

Execution · Practiced Mastery
A Tetris variant testing placement speed with a square-building scoring layer.
Hollow Knight leans Execution (Practiced Mastery); The New Tetris 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.
Hollow Knight
Precise platforming and pogo timing dominate hard content.
The New Tetris
Fast precise placement under speed is the lead axis
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hollow Knight
Bosses run scripted attack pools; not adaptive.
The New Tetris
Multiplayer adds light prediction, mostly solo speed
The New Tetris leans a little harder on variance, though the gap is small.
Hollow Knight
Negligible; world layout is fixed.
The New Tetris
Piece bag is random but bounded and mappable
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.
The New Tetris
Building 4x4 squares for bonus rewards deeper 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.
