Great translation! Thank You!
Few questions/suggestions:
Everything may slip down through my fingers like sands
"sand", not "sands"."sand"doesn't have plural form
(I think...)
And I only wait the time passing by so calmly
I don't quite understand this line... what does "waiting the time" mean?
I had made this game a little longer than usual
No problem, I'll be able to find another one
"Another one"? Does she mean "another game"?
