Lovely story, Zeleira! This is awesome:

That each universe had its own space might be intelligible, but that each dimension of the universes had the same energetic beings "living" similar stories over and over again, as if it were a grotesque play in which all are only actors, was something absurd, a macabre game where change is the only constant.

This especially leaped out at me:

the essence of the game between life and death is not macabre, it is magical and labyrinthine...

I love an upbeat or hopeful ending.
