Believe me. I am looking into it. Right now my options towards adding actual hentai/sexual images are to hire an artist to make the scenes (which requires money to commission and a dedicated artist). Or do the artwork myself. I have no artistic talent when it comes to digital hentai artwork. Even if I self teach myself 3DCG maker as shown earlier, I am not satisfied atm with what the program can achieve.
One solution would be to make a Sex Quest patreon. Any funds I acquire through that would absolutely go towards commissioning sexy artwork.
However, I don't want to go through all the work of making a patreon/blog only to find out no one is interested in funding my silly lil Sex Quest. That is part of my reasoning to why I am posting updates here for free. To gauge interest and ultimately decide if making a patreon and taking this project more seriously would be worth the time and hard work.
As I've said, Sex Quest is my first project I ever worked on to this extent and even shared with others so I don't want to get in over my head from the get go.
That being said, I AM searching for immediate solutions to making the game sexier than just text. Sprite sex? More looking into 3DCG maker? Who knows. I appreciate any advice or suggestions on topic though! At this point there are NO bad ideas.
