given how long the chapter is, have you considered steam? they have other VNs there and might get the series a bit more attention.
Sorry, I somehow missed your question. My game cannot go on Steam because of the software I use to create the graphics. It is a license/trademark issue. Most adult VN's you find on Steam were done using a program called DAZ3D, which does not have this limitation. I don't use DAZ because I don't like the way the characters look.
