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

Optimization · Pure Optimization
Methodically mapping a fixed labyrinth while managing levelling and gear economy.

Optimization · Pure Optimization
A farm-life sim solved by season routing and profit optimization.
Shining in the Darkness leans Optimization (Pure Optimization); Stardew Valley leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Shining in the Darkness
Menu-driven turn battles need no dexterity
Stardew Valley
Trivial timing on fishing and combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Shining in the Darkness
Monsters follow fixed behaviour tables
Stardew Valley
No adaptive opponent exists
Shining in the Darkness leans a little harder on variance, though the gap is small.
Shining in the Darkness
Maze layout and random encounters are unknown until mapped
Stardew Valley
Crop luck and geode RNG matter modestly
Stardew Valley leans a little harder on optimization, though the gap is small.
Shining in the Darkness
Mapping the labyrinth and grinding gear efficiently is the game
Stardew Valley
Routing seasons, profit loops, and bundles dominates
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.
