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.

Optimization · Light / Casual
A narrative horror-investigation game where uncovering the mystery outweighs any mechanical challenge.

Execution · Light / Casual
A comedy sandbox testing nothing harder than enthusiasm for collateral damage.
Call of Cthulhu leans Optimization (Light / Casual); Kill It With Fire leans Execution (Light / Casual).
Kill It With Fire leans a little harder on execution, though the gap is small.
Call of Cthulhu
light stealth timing, mostly minor
Kill It With Fire
Swatting spiders needs only loose aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Cthulhu
no opponents, narrative investigation
Kill It With Fire
Spiders scuttle on simple RNG, no minds here
Kill It With Fire leans a little harder on variance, though the gap is small.
Call of Cthulhu
skill checks add randomness
Kill It With Fire
Spider hiding spots are unknown until flushed out
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Cthulhu
stat allocation lightly solvable
Kill It With Fire
Checklist objectives and weapon unlocks, deliberately shallow
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.
