head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Light / Casual
A relaxed hidden-object hunt for cats across hand-drawn scenes.

Optimization · Light / Casual
A point-and-click detective adventure where puzzle logic is the entire test.
100 Ninja Cats leans Optimization (Light / Casual); 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.
100 Ninja Cats
Clicking to find hidden cats, no twitch demand
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.
100 Ninja Cats
Solo with no opponent to predict
Circle of Blood
no opponents, puzzle-driven
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
100 Ninja Cats
Cat locations fixed, just hidden until spotted
Circle of Blood
no meaningful randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
100 Ninja Cats
Systematic searching of scenes is the only system
Circle of Blood
inventory puzzle logic is solvable
