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 neo-noir one-hit-kill action platformer about planning and replaying perfect assassinations.

Execution · Pure Mechanics
A Tetris variant collection testing piece-placement speed and stacking.
Katana ZERO leans Execution (Practiced Mastery); Tetris Party leans Execution (Pure Mechanics).
Tetris Party leans a little harder on execution, though the gap is small.
Katana ZERO
One-hit-death slashing and deflects demand precision
Tetris Party
Precise fast piece placement decides every game
Tetris Party leans a little harder on reads, though the gap is small.
Katana ZERO
Enemies follow fixed placements and behaviours
Tetris Party
Versus mode adds slight attack-timing prediction
Tetris Party leans a little harder on variance, though the gap is small.
Katana ZERO
Rooms are identical on every attempt
Tetris Party
Piece bag is random but bounded and mappable
Katana ZERO leans a little harder on optimization, though the gap is small.
Katana ZERO
Planning the perfect room-clear sequence
Tetris Party
Stacking strategy has known optimal patterns
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.
