A branching story that tests choice exploration more than any skill.

Optimization · Light / Casual
A wordless atmospheric pilgrimage across dunes toward a distant mountain.

Branching script, no adaptive adversary
Journey
Anonymous companions cooperate, never oppose
Detroit: Become Human leans a little harder on variance, though the gap is small.
Detroit: Become Human
Branch consequences are hidden information until explored
Journey
World is fixed and linear
Detroit: Become Human leans a little harder on optimization, though the gap is small.
Detroit: Become Human
Flowchart completion is a light solvable puzzle
Journey
Light scarf-collecting routes at most
