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 children's hidden-object game about spotting items from rhyming riddles.

Optimization · Systems & Chaos
A teenage drama built around rewinding decisions to map which choices actually alter the scripted outcome.
I Spy Fantasy leans Optimization (Systems & Chaos); Life is Strange 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.
I Spy Fantasy
Clicking found objects, no dexterity
Life is Strange
Rewind mechanic removes virtually any failure state
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
I Spy Fantasy
No opponent to model
Life is Strange
Scripted teen drama; no opponent models the player
Life is Strange leans a little harder on variance, though the gap is small.
I Spy Fantasy
Object placement varies but is fixed per scene
Life is Strange
Rewind obscures which choices are truly consequential
Life is Strange leans a little harder on optimization, though the gap is small.
I Spy Fantasy
Systematic scanning to find riddle objects faster
Life is Strange
Understanding consequence chains enables deliberate dialogue path planning
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.
