well, this was worth a download and then some! I haven't played an adult game this good since free cities! The only thing bad about it really is my dick is so god damned sore, shouldn't have started playing this on my weekend.
Some suggestions, if I were to be so bold...
I would like some more options for the dungeon for certain characters. Lin enjoys a certain fetish, but it seems that Ashley has that fetish option for the dungeon and not Lin. Likewise with Android's end fetish.
Stronger fetish support all around would be nice, certain girls get off more on some things than others, and adding in more scenes to reflect that, or give me a choice on what position we do things in for generic "have sex" scenes would be good. ex, using lin's little elf butt instead during
A watersports fetish could be an option, a little easier to do than pregnancy, which I think sounds very difficult! But fun, if you can manage it.
The writing is superb, keep it up for the characters, we are hitting sol levels of fun here so even if you feel that you don't have a good plot idea for one of the characters, we still want to see what they're up to, and have a chance to interact with them.
Besides "more more more more!" I think adding some things to purchase could be a way of making a bit more money, dlc and the like. I know, a bit anti consumer, but there was a lot of love put into a game which was free, I would not begrudge you wanting to make some cash on this project!
