That's awesome! No worries about late replies, you're an indie dev making (relatively) niche nsfw stuff and (at least for now) releasing it to the public for free.
You owe nothing to anyone - though, speaking of that, what would the best way to support you be? This is one of very few NSFW games I've played in a while that are good specifically for being an NSFW GAME, as opposed to being better suited as a sfw game or NSFW non-interactive media, and I very much would like to encourage more such creativity!
