Hello ! I downloaded the game months ago and only just played it (i have only up to chapter 3 so this may have been fixed), but in the scene where mc (wake, i believe) has blue eyes and is in byrus' home, the maid says "ta guele". However, it should be "ta gueule" for it to be an actual french shut up, hope it helps (also, amazing game, love the story, the jokes and everything, music is good, as you said, and there's a lot of cultural references I love, keep going !
