Meaning of the title

[Wang Tang]

I just finished the game, beautiful and fun albeit a bit empty, and the massive difficulty spikes in the mask boss battles was atrocious.

One mystery remains: I found myself wondering about the title "Bridge of Spirits". What does it relate to?

Kena is the connection (bridge) between the realm of living and the spirit one. She must put at peace the spirit still stuck between life and death.
