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
Anxiety-fueled block-climbing puzzler wrapped in a relationship-drama narrative.

Optimization · Practiced Mastery
A 2D Souls-like with metroidvania exploration.
Catherine leans Execution (Practiced Mastery); Salt and Sanctuary leans Optimization (Practiced Mastery).
Catherine leans a little harder on execution, though the gap is small.
Catherine
Climbing block towers fast under time pressure
Salt and Sanctuary
Souls-like timing in 2D
Salt and Sanctuary leans a little harder on reads, though the gap is small.
Catherine
Versus mode exists but is niche
Salt and Sanctuary
Scripted bosses with telegraphs
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Catherine
Some randomized block layouts on replays
Salt and Sanctuary
Loot drops
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Catherine
Block-technique vocabulary solves each tower
Salt and Sanctuary
Skill tree builds and gear routing
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.
