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 · Light / Casual
A point-and-click detective adventure where puzzle logic is the entire test.

Optimization · Systems & Chaos
A casual hidden-object adventure testing visual search and light puzzle solving.
Circle of Blood leans Optimization (Light / Casual); Clockwork Tales: Of Glass and Ink leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Circle of Blood
no physical skill, point-and-click
Clockwork Tales: Of Glass and Ink
Clicking hidden objects has no dexterity requirement
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Circle of Blood
no opponents, puzzle-driven
Clockwork Tales: Of Glass and Ink
An authored steampunk plot with no adversary
Clockwork Tales: Of Glass and Ink leans a little harder on variance, though the gap is small.
Circle of Blood
no meaningful randomness
Clockwork Tales: Of Glass and Ink
Object placements are unknown only until spotted
Clockwork Tales: Of Glass and Ink leans a little harder on optimization, though the gap is small.
Circle of Blood
inventory puzzle logic is solvable
Clockwork Tales: Of Glass and Ink
Hidden-object scenes and minigames have fixed findable solutions
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.
