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 shmup collection testing reflexes and dodging against memorizable bullet patterns.

Execution · Pure Mechanics
A melee-heavy sci-fi horror game where reactive parry timing and dodge reads dominate over system depth.
Shooting Love, 200X leans Execution (Pure Mechanics); The Callisto Protocol leans Execution (Pure Mechanics).
Shooting Love, 200X leans a little harder on execution, though the gap is small.
Shooting Love, 200X
Dodging dense bullet patterns at speed is the whole test
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.
Shooting Love, 200X
Enemy waves are fixed patterns, not adaptive
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.
Shooting Love, 200X
Some spawn variation but largely memorizable
The Callisto Protocol
Some loot containers and drop variability add mild uncertainty
Shooting Love, 200X leans a little harder on optimization, though the gap is small.
Shooting Love, 200X
Scoring systems and routing reward optimal play
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.
