Not gonna lie, there would be a lot of things to nitpick, but I don't wanna focus on that. Instead, I would like to express my thoughts on the potential. You got absolutely amazing wifey here, physically speaking, and I've seen a lot of otherwise not great games be carried by such fact alone. Visuals in general is a definite strong point for this game, however I fear that sandbox will hold it back, at least in the current rough shape. You gotta ask yourself, if the task of its maintenance is worth it. I think in Visual Novel format this would be a lot better experience. And there should be some choices, even if illusion of choice, some flavor text alterations, anything to give player the feel that we have any form of control... not to be a control freak, but to feel involved in the story. I am probably not great at explaining this, but large reason why people play smut games rather than watch videos is that important thing of making choices, feeling like you are steering the story in ways that you fantasize about. Will check back next couple of updates and hope to see things improve, good luck!
(this is just my opinion and initial impressions, goal was not to demotivate, i believe in the potential keep at it)
