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 · Systems & Chaos
A casual hidden-object hunt through an underwater city testing visual search patience.

Optimization · Light / Casual
A point-and-click detective adventure where puzzle logic is the entire test.
Abyss: The Wraiths of Eden leans Optimization (Systems & Chaos); Circle of Blood leans Optimization (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Abyss: The Wraiths of Eden
Pointing at hidden objects takes no physical skill
Circle of Blood
no physical skill, point-and-click
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Abyss: The Wraiths of Eden
Scripted underwater ghosts, nothing adapts
Circle of Blood
no opponents, puzzle-driven
Abyss: The Wraiths of Eden leans a little harder on variance, though the gap is small.
Abyss: The Wraiths of Eden
Scene contents are hidden only until searched
Circle of Blood
no meaningful randomness
Abyss: The Wraiths of Eden leans a little harder on optimization, though the gap is small.
Abyss: The Wraiths of Eden
Each hidden-object scene and puzzle has one fixed solution
Circle of Blood
inventory puzzle logic is solvable
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.
