head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Execution · Pure Mechanics
A bullet-hell action-adventure testing dodging and platforming precision through hostile arenas.

Execution · Pure Mechanics
A melee-heavy sci-fi horror game where reactive parry timing and dodge reads dominate over system depth.
Luna Abyss leans Execution (Pure Mechanics); The Callisto Protocol leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Luna Abyss
Bullet-hell dodging and platforming demand precise inputs
The Callisto Protocol
Melee-parry timing and dodge-direction choices are the core skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Luna Abyss
Enemies are scripted, not adapting to you
The Callisto Protocol
Mutants follow telegraphed scripted attack patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Luna Abyss
Some randomness in bullet patterns and encounters
The Callisto Protocol
Some loot containers and drop variability add mild uncertainty
The Callisto Protocol leans a little harder on optimization, though the gap is small.
Luna Abyss
Weapon and movement mastery reward planning
The Callisto Protocol
Weapon upgrades and credit management have limited depth
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.
