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

Execution · Light / Casual
An interactive wordless short story with essentially no skill test.

Execution · Light / Casual
A narrative adventure where quick-time events punctuate an otherwise story-first experience.
A Bird Story leans Execution (Light / Casual); Indigo Prophecy leans Execution (Light / Casual).
Indigo Prophecy leans a little harder on execution, though the gap is small.
A Bird Story
Walking through scenes is the only input
Indigo Prophecy
QTEs require light timing precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
A Bird Story
No opponent of any kind
Indigo Prophecy
no opponents, narrative branches only
Indigo Prophecy leans a little harder on variance, though the gap is small.
A Bird Story
Wholly linear with nothing hidden mechanically
Indigo Prophecy
minimal randomness in outcomes
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
A Bird Story
Nothing to solve; it is a told story
Indigo Prophecy
few solvable systems, story-driven
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.
