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

A hidden-object adventure about solving fixed environmental and inventory puzzles.

Optimization · Pure Optimization
Sci-fi thriller played as the station AI solving its own crisis.
Lost Lands: Dark Overlord leans Optimization (Pure Optimization); Observation leans Optimization (Pure Optimization).
Observation leans a little harder on execution, though the gap is small.
Lost Lands: Dark Overlord
Point-and-click; no timing or aim demands
Observation
Camera control and interface manipulation
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Lost Lands: Dark Overlord
Solo with no adaptive adversary
Observation
Events are fully authored
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Lost Lands: Dark Overlord
Hidden objects and clues unknown until found
Observation
Mystery unknown until uncovered
Lost Lands: Dark Overlord leans a little harder on optimization, though the gap is small.
Lost Lands: Dark Overlord
Solving fixed inventory puzzles is the entire game
Observation
Systems puzzles and station schematics solving
