Here is my personal incest patch. It doesn't require a specific version of the game, but it's always okay and uses the simple ".replace" function in python which allows you to replace words in text files (such as dialogs). So Julia becomes Mom, Lucy -> Sis, Emma -> Aunt Emma etc. (Just unzip it in the "game" folder).
EDIT:
I made a small improvement to my patch (V2). There shouldn't be more dialogues (I hope), in which the other characters (other than the protagonist), speaking with Julia for example, refer to her as "Mom" (the same applies to Emma, Lucy, etc).
UPDATE
Version 1 actually works with the new game (0.60) as well, but with the old dialogue problems. Version 2 strangely doesn't works, but I don't know why yet. Something has certainly changed in the dynamics of the dialogues, which are always problematic in this game for several reasons: sometimes the names derive from the values of the game variables ([sRocky.name] or [sRockyT.name], [sJulia.name] or [sJuliaT.name] ...) are sometimes present directly in the translation dialogs (with the text "Julia" directly for example). Making a direct change of the text "Julia-> Mom" is not possible because then some information wouldn't be loaded (such as images because the game would look for a "sMom" that doesn't exist instead of "sJulia") ... So for now it's hard to change if I don't understand the new dynamics.
