Since
KoGa3 has removed his mod, I've used it and updated it to v0.18
This verstion contains hard coded incest and a walkthough for the game (not that there is an outcome from any choices at the present time other than scenese missed!). Also, only the MC can be renamed.
You may need to start a new game since it appears that some of the orignal mod puts variables in the save games and complains about music files missing.
I've tried to mitigate this as much as I could but it was still happening for me with older saves from time to time - You have been warned!
To install overwrite the existing game\script.rpy file with the one in the zip file.
