There's only a few scenes but the model is pretty hot and I like the direction the game is taking. It's honestly more of a 3.5 but I'm giving it 4 stars due to its potential.
The dialogue is a little lacking, there isn't much of a rapport between the MC and his wife and the game seems to prefer to rush to the 'sessions' more than exploring the themes of an NTS couple.
I think the game would flow a lot better and be hotter if after these sessions the MC and Kaede talked about it, what they liked about it, what their boundaries are, teasing, establishing expectations.
All of this builds believability and tension, atm it sort of plays out like a gallery selector without the UI for it. The developer isn't a bad writer, just that I feel he's rushing things.
