I'd like to eventually add more, but I'm broke.
The problem with making a Patreon is that I don't know if I could realistically create enough content per month to justify charging people for it. Patreon also has strange rules regarding noncon/dubcon content, so I don't know if a game like this would even be allowed.
It's not a selfish wish to want me to have a Patreon, though - in fact, it's the opposite. You want a convenient way to give me money, which is kind of you.
