head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Solving fixed light-and-shadow coordination puzzles at a forgiving narrative pace.

Optimization · Pure Optimization

Platforming is light and forgiving.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Shady Part of Me
No opponent - a solo narrative puzzle journey
Spiritfarer
Spirits follow scripted arcs.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Puzzles are fixed and fully visible once reached
Spiritfarer
Minor resource RNG.

Shady Part of Me
Coordinating girl and shadow through light logic is the game
Spiritfarer
Boat layout and crafting loops reward planning.
