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 fast falling-block puzzle testing speed placement and chain planning.

Execution · Pure Mechanics
A melee-heavy sci-fi horror game where reactive parry timing and dodge reads dominate over system depth.
Raining Blobs leans Execution (Practiced Mastery); The Callisto Protocol leans Execution (Pure Mechanics).
The Callisto Protocol leans a little harder on execution, though the gap is small.
Raining Blobs
Fast block placement under accelerating speed decides runs
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.
Raining Blobs
Optional versus but mostly solo, little prediction
The Callisto Protocol
Mutants follow telegraphed scripted attack patterns
Raining Blobs leans a little harder on variance, though the gap is small.
Raining Blobs
Falling blob colors are random but quickly mappable
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.
Raining Blobs
Chaining and clearing patterns has known 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.
