That's one of the reasons why I started this project. I was (and still am) an avid lover of VNs, and just like you, I was fed up with the generic plots that came out one after the other, especially the ratio of 10% story and 90% bodily fluid exchange. So 'cause I didn't want to be that guy who goes on to the forums and starts b*tching and moaning like an entitled prick, I started tinkering around with the tools that you can create Vns with, eg. coding, rendering, 3D sculpting, PS postwork, animation, etc. When I thought I reached an acceptable level after around 1.5 years, I wrote down the rough storyline (the original was around a 100 pages draft), focusing almost solely on the characters. That is also one reason why the first real xxx scene appears much later in the game.
Fun fact, the Bi/Gay storyline was not planned originally, it is an addition due to one of my oldest patrons on Patreon "pushing" me to do it. You can imagine how interesting was the learning curve for a straight male like me, plunging myself into a whole new world of same-sex relations. But luckily it seems to pay off 'cause the feedback is super positive from the community so far.
