This is kind of a happy accident; this game is one I played before in Spanish from Ectocomp, but it happened to match the 2023 French Comp themes of treason and archives, so it was translated and entered into that as well.
This is a compelling story, which involves a soldier that is obsessed with collecting the letters of other soldiers, usually after they die. He wants to write his own letter, the best letter ever, and will stop at nothing for his goals.
There are 3 acts, each one fairly brief with actions that are generally clued in the instructions or text. I found it easier in French than in Spanish, to be honest.
Overall, the obsession here is very compelling.
