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

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

Execution · Light / Casual
A short interactive love story told through tactile vignettes rather than challenge.
A Bird Story leans Execution (Light / Casual); Florence leans Execution (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
A Bird Story
Walking through scenes is the only input
Florence
Gentle touch vignettes with no fail state
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
Florence
No opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
A Bird Story
Wholly linear with nothing hidden mechanically
Florence
Fully linear story
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
Florence
Nothing to solve; you experience it
