This is an important story. Please finish it and try to get it on Steam and GOG. People need to play this game. In 0.3 the way you have done the story is sublime!
I agree with your point about 90% of AVNs are never finished, on the other hand, games that are finished tend to sell very well. When you look at the top-selling AVNs. like Acting Lessons, for example, so that may bode well for you. It must also be frustrating as it obviously hurts the AVN genre. So good luck with this, and please make a big deal about the main character being transgender. You will lose a few sales, but you will make many more extra sales!
