I've started to make a complex quest system which will allow you to have a lot of talking options with the girls. Depending on your answers and background the dialogs will be differents.
I have hidden the dialogs because they might change and because I don't like to spoil people.
I'm progressing quite fast on these interactions. This quest system should be finished in 2 or 3 days maximum. The other things like video rendering and new scenes will not take that much time. So I'm following my schedule for the moment. I should be able to release the update before 15 of april.
