Incredible, to be just a demo I liked it and it promises a lot.
I would have liked it to be a little longer, but we just have to wait patiently for the final version, An improvement would be to add animated sprites, it would be very good and also they look great in NTR games.
I really liked the idea of having Sana's image on the game screen and see when she is being abused and explore the city to find the event, I hope they do more events like that
