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 Korean-mythology patterns.

Execution · Pure Mechanics
A melee-heavy sci-fi horror game where reactive parry timing and dodge reads dominate over system depth.
Shikhondo: Soul Eater leans Execution (Pure Mechanics); The Callisto Protocol leans Execution (Pure Mechanics).
Shikhondo: Soul Eater leans a little harder on execution, though the gap is small.
Shikhondo: Soul Eater
Weaving through dense bullet patterns is the entire game
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.
Shikhondo: Soul Eater
Bosses fire scripted patterns, not adaptation
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.
Shikhondo: Soul Eater
Some spawn and item-timing randomness
The Callisto Protocol
Some loot containers and drop variability add mild uncertainty
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Shikhondo: Soul Eater
Pattern memorization and scoring routes reward study
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.
