head to head
Katana ZERO asks more than Tetris DX, and the gap is optimization.

Execution · Practiced Mastery
A neo-noir one-hit-kill action platformer about planning and replaying perfect assassinations.

Execution · Pure Mechanics
Tests perceptual speed and motor execution under accelerating piece gravity.
Katana ZERO leans Execution (Practiced Mastery); Tetris DX leans Execution (Pure Mechanics).
Tetris DX leans a little harder on execution, though the gap is small.
Katana ZERO
One-hit-death slashing and deflects demand precision
Tetris DX
Precise placement under accelerating gravity decides every game
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Katana ZERO
Enemies follow fixed placements and behaviours
Tetris DX
Solo stacking with no opponent to model
Tetris DX leans a little harder on variance, though the gap is small.
Katana ZERO
Rooms are identical on every attempt
Tetris DX
Random pieces are bounded and rapidly mappable
Katana ZERO leans clearly harder on optimization.
Katana ZERO
Planning the perfect room-clear sequence
Tetris DX
Stacking patterns and scoring strategy are well solved
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.
