have played only the LN one. Worth replaying?

Could someone please tell me how I unlock the last achievement, "Vague memory"? I;ve tried entering any name that I could think of but I can't manage to get it right. Is there something I'm missing, or is the achievement only known to a certain few? Thank you in advance!...

found a little typo shortly after the start: "it´s unbelievable cold and she is all by herself" > should be fixed to "unbelievably cold"

idk why but the game shows no achievements till i go into the page, can i can't highlight it on my profile, idk if this is a steam thign or what but it would be cool to have it in my profile!!

I would like to know if a Spanish translation of the game is planned
