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 · Pure Mechanics
A high-intensity twin-stick shooter testing sustained aim and combo-chain routing.

Execution · Practiced Mastery
A neo-noir one-hit-kill action platformer about planning and replaying perfect assassinations.
Assault Android Cactus leans Execution (Pure Mechanics); Katana ZERO 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.
Assault Android Cactus
Screen-filling enemy waves demand constant twin-stick precision
Katana ZERO
One-hit-death slashing and deflects demand precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Assault Android Cactus
Robot waves spawn on fixed scripts
Katana ZERO
Enemies follow fixed placements and behaviours
Assault Android Cactus leans a little harder on variance, though the gap is small.
Assault Android Cactus
Power-up drops add minor run-to-run noise
Katana ZERO
Rooms are identical on every attempt
Katana ZERO leans a little harder on optimization, though the gap is small.
Assault Android Cactus
Combo chains and battery routing are learnable scoring systems
Katana ZERO
Planning the perfect room-clear sequence
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.
