In Damsels and Dragons you play a man who is managing a group of female adventurers -- 4 at first, but more as time goes on -- forming parties, sending them on adventures, getting them magic items, etc.
Over time you will gain the affection of your adventurers, learn to cast spells, and engage in acts of lust and perversion. ;)
What's in the 0.1 release?
4 character classes, each with its own combat abilities, and erotic renders.
A dozen or so monsters, most of which have graphics, but some of which are using placeholders.
Three spells you can cast.
Four different fetishes -- Exhibitionism, Voyeurism, Masochism, and Submission, that the girls can acquire through adventuring and will affect how they behave. Note that if a fetish doesn't appeal to you, you never have to pursue it -- there are always opportunities to be vanilla with a girl, as well as a spell that removes a fetish and gives a girl increased sex drive in exchange.
Two areas to explore that function slightly differently and have different monsters. The dungeon is predictable, offering a couple easier fights followed by a tough one that can get you a magic item. The woods is more random and free form.
The very raw beginnings of a story.
