A bit of a disclaimer, I don't speak French, so I might not be your target audience. I was blocked at the key part, I went all around but I couldn't figure out what to do, but I didn't want to cheat with google translate.
I liked the reviews on the game page tho.
Regarding the game, I like the rhythm and the building tension on screen changes. I really liked how the text conveys / visualises the personality or the mood of each person. The game is visually consistent and simple, I think "better graphics" would take away from this feeling you get from the text fiddle animation so it was a good pick.
