I love everything about this game, its a bit short but that comes with it being incomplete of course so keep up the good work. No criticisms from me about the character models other than wishing they would be more expressive.
As for fetishes I/we would like, what are your limits? It all depends on that. You should make the game as you like it, with partial appeals to the audience. I do have some requests if you will, and these are purely personal preferences. Could you maybe make Robyn's member a bit larger? What is the possibility of making her a full-on futanari? Will you be bringing in any taboos into the equation, like adding more family to the equation or adding upon Anita's situation with her father?
Otherwise, this is certainly an amazing game so far. Don't understand why some people take jabs at talented creators who give them games for free.
