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 · Practiced Mastery
Arcade boss-rush testing pattern execution and weakness-order knowledge.
Katana ZERO leans Execution (Practiced Mastery); Mega Man: The Power Battle leans Execution (Practiced Mastery).
Katana ZERO leans a little harder on execution, though the gap is small.
Katana ZERO
One-hit-death slashing and deflects demand precision
Mega Man: The Power Battle
Boss pattern dodging at arcade pace tests the hands
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
Mega Man: The Power Battle
Robot Masters cycle fixed movesets
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Katana ZERO
Rooms are identical on every attempt
Mega Man: The Power Battle
Boss selection order barely changes the run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Katana ZERO
Planning the perfect room-clear sequence
Mega Man: The Power Battle
Weapon-weakness ordering is a solvable puzzle
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.
