Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Practiced Mastery
A comedic first-person exploration romp cataloguing a candy-coloured alien planet.

Optimization · Practiced Mastery
Wordless environmental puzzle decoding in a hostile world, with minimal combat demands.
Journey to the Savage Planet leans Optimization (Practiced Mastery); Scorn leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Journey to the Savage Planet
Light shooting and platforming, forgiving
Scorn
Clunky combat exists but avoidance usually suffices
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Journey to the Savage Planet
Creature AI is simple and scripted
Scorn

Some unknown creature behaviours on first contact
Scorn
Opaque machinery puzzles are hidden logic until decoded
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Journey to the Savage Planet
Upgrade routing and scan-everything exploration
Scorn
Deciphering each biomechanical puzzle has one fixed solution
