The developer is a she and she lives in Russia as far as I know. Things are a bit slow atm for obvious reasons. Stopping pledges won't speed up the game. In fact it will slow it down even further or even get it abandoned.
They have been just as slow before without reasons. But feel free to keep paying, it's everyones own decision in the end.
I for my part buy games mostly once they are finished and land on GOG or Gamejolt (well ... not anymore, since Gamejolt banned adult games) or itch.io, sometimes I even buy an adult game on Steam, even if I hate that. I also help finance quite a few games on Kickstarter (ok, non adult ones. Currently waiting for 5 to be finished). In short: I don't do recurring payments.
And the "she" thing is a rumor based on a Twitter or Discord account. Those who understand the language however say that the pronouns and gramma match a male writer and after playing her/his previous game I tend to agree. But in the end it doesn't matter if he's a she or binary or whatever.
