I like this thing, but storywise what we got beyond the first release was meh. I know conjuring up a somewhat coherent story is the most difficult part of these VNs, but the amount of action currently in is not enough to make up for the lack of direction. So i would say you should either release a mini comic per week or something, or adjust the price to more affordable (to reflect the price/content ratio) for each pro update, you would probably have more constant patrons that way. Take it slow with story and build tension, or go all out, but then you'll need a lot more renders and animations and exciting scenarios to hold interest.
