I'm from the US - initially the game was just called Luz because I liked the way it sounded, then I changed it to Luz Azul because it's a palindrome and I thought it worked with the mirrored-reality theme. And worked for the black white and blue color palette!
I have to admit the name is very stylish and fitting. I didn't even notice it was a palindrome. I also really loved the cover art, you did a fantastic job with presentation.
"Luz Azul" means blue light in portuguese and spanish (and probably other latin adjacent languages), that is why I asked where you were from
