The game has a primary plot, introduced during the Prologue, where there's some sandbox but a ton more like a standard VN. After some time, though, you then are given all kinds of distractions: pimping the MC out to elderly women; pimping the MC out to trans and gay characters; trying to blackmail girls when you've previously tried to increase love and affection only; and so on. There seems to be a heavy lack of focus by the dev, at least if you play update by update.
What I'm hoping is that VileLab has several mostly-fully-developed plotlines throughout the game, each of which he works a bit on and then rotates to another plotline. If that's true, by game's end you might be able to play a single path through the game without getting stuff that doesn't make sense on the path you've chosen. In that case, I could see it being fun to play through on a single plotline, with as many PTs as you want for other alternatives that might exist.
However, even though I hope for the above, as things are now I won't hold my breath. There's far to much forced content that doesn't match prior choices, so things feel extremely messy and unorganized. So there's a strong chance that, even after this is completed, it will be unenjoyable in many respects. It's frustrating as a player to make choices that then later are ignored. This game seems to do a lot of that right now.
