Awesome game you've made, probably one of the best out there. Will you make a more walkthrough or some hints towards how to get the remaining pictures?
Besides that a proper save function could be added to help runs, specially with Cathryn, that you have to just keep trying and trying to find out the routes you didn't go to.
And just a wish of mine to have a more "sneaky" NTR, in which the MC doesn't know until a lot later or he doesn't discover at all, in which you get context by other means or by subtle hints in the pictures or texts.
Thanks a lot for making the game, the quality of the art is superb and so good, besides the story which is immersing and gives an opportunity to empathize and feel what the MC and the girlfriend are going through. <
