Don't hold your breath... you and I seem to be the only two Maple fans in existence.

She's probably never going to win the poll. I think on top of that, all the Patreon TOS silliness has probably thrown enough of a scare into the Nuts that they'll just avoid ever adding more content for her. The fact that they had to add special dialogue to the existing Maple scene was so utterly ridiculous. If I were a dev I would never want to waste a minute of my time creating art and coding for scenes that I might have to later go back and delete from the game to protect myself from legal or financial risk. It sucks but this is just the reality of H games being made using Patreon money.
Maybe if we're lucky we'll get another "pinup" shot of her from Lambert. That way it's easy to remove if they have to.
