TL;DR:
(Disclaimer: the game is still in-development as I have reviewed it, the review will be updated & revisited after it is finalized)
Pros:
1. The plot is fun.
2. Ren'Py system, basically, "rape-it-all-the-way", 0 diversion
3. No grinding for H-Scenes
Cons:
1. The so-call mini-games...is not as good as you might be expecting if you are looking forward to something cool.
2. You might enjoy like the easy & straight-forward style, there is basically no choices at all nor any consequences.
Honest Opinion:
Given that the popular opinion might be that this game is easy to access and straight-forward, I will probably be the black sheep who has a different view.
Personally, 3D models are easily made and simply required minimal effort to design, so I am giving it a low score for the art and graphic, you might say "you can at least appreciate the details in the background" but then I'd rather appreciate the art teams' hardwork for whatever the cost.
Audio wise, there is no innovation at all as there is no VA. So again among all the other Ren'Py games, this is not one that gives me a good impression.
Writing wise, it's quite fine. You can ask for more if you are an erotic novel fans, but I am satisfied with the writing.
What hurts me most is that the whole game is too straight-forward. There is no choices that affect the outcome and somehow create variations. If there are truly not many differences, there shouldn't be so many trivial game controls like moving via locations, doing certain actions, etc. Those gimmicks don't make any sense at all. By creating a false sense of control, doesn't mean the players are in control at all, and frankly, those meaningless gimmicks make the game longer than it should. So more is less in this case.
