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 · Pure Mechanics
A bullet-hell shooter testing precise dodging through scripted bullet patterns.

Execution · Practiced Mastery
Memorising spawn patterns then executing them flawlessly under one-hit-death rules.
Akai Katana leans Execution (Pure Mechanics); Super Contra leans Execution (Practiced Mastery).
Akai Katana leans a little harder on execution, though the gap is small.
Akai Katana
Threading through dense bullet curtains demands flawless precise movement
Super Contra
One-hit deaths demand precise dodging and constant accurate fire
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Akai Katana
Enemy bullet patterns are scripted, not an adapting mind
Super Contra
Alien waves follow fixed spawn scripts
Akai Katana leans a little harder on variance, though the gap is small.
Akai Katana
Patterns are fixed once learned, minimal true randomness
Super Contra
Nothing random once spawn patterns are memorised
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Akai Katana
Scoring systems and route memorisation reward deep optimization
Super Contra
Memorising spawns and weapon routes is half the run
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.
