Also i'm not complaining for the lack of sex scene but i think it'll be awesome if u put a disclaimer in the beginning of the game to let the players know about it, i know there is tags but most people probably only see the rating before downloading. Or another alternative is to put sex scene in a dream sequence, as of now its pretty obvious that MC is lusting for the girls and it will make complete sense for him to wet dreams of them, and the best part is that its not really canon and only act as a fan service. Considering that, it was also cool to wait for the right moment and make the first sex scene special cause the dream sequence could ruin the anticipation for the actual sex scene.
All in all i really admire your work and wish the best of it, i personally encourage you to not listen to the haters and take your time in the development.
