Well...This was very short. I like the themes, so that's not a problem to me. However there is a few things even in the demo I want to talk about/address:
1) the first bit about the verifying age is a bit ambiguous of what you're trying to do. Given your target audience, its a bit understandable some people might mistake how that "option" works, instead of a standard yes/no
2) the preview scenarios look intriguing, but it doesn't actually tell me anything about where you want this game to go. Are those possible story lines, are they where you will wind up, is that NPCs we're going to interact with?
3) Going into the male part, there is zero content, and you start with a female sprite to begin with. Does that mean there is no male option and its probably on the back burner? Is that content going to be something that lags due to your lack of interest in it? You mentioned its your first time allowing a choice in gender. That's a bit of a yellow flag for me, because anytime a dev tries to branch out to appease an audience, I find in my experience they burn out faster and lose motivation for the project altogether.
