You mentioned other monetization options in your post. Would you consider starting a Kickstarter campaign and/or selling merchandise of your game?
I don't think I'm in the position to run a Kickstarter, honestly. TwT
As far as merchandise goes, that's also quite a complicated topic... the other week, as a joke, I talked with a few other VN creators about making a shared line of plushies of our VNs' characters. It was a crack idea, but who knows. =V
But really, it's definitely a thought that ever crossed my mind. We'll see how things develop from here and, if there's a big demand for it and some profits to be made, maybe we'll actually go through with it at some point.
