Overall, it's worth giving it a try, but the English text needs some improvisation, as it seems to have been clearly translated by AI.
I don't agree that it is "a weak Niramare Quest." In my opinion, it's at least on par with Niramare if not better. First of all, the story plot is actually better than that of Niramare. The developer attempts to create a comedy, and it genuinely works, I had a few LMAO moments, or at least more enjoyable than Niramare. However, the English text still needs some improvisation due to its AI translation (Consider Niramare is also AI-translated, and even worse than this one. This game does not seem to be that bad.).
So the story is a 4/5 (not considering the poor AI translation, just for the story plot itself)
CG in this game is not like Niramare (where most of the scenes are mere"change the head of a character can call it a new CG"). Every CG is different from the others just like a normal RPGM game. However, it appears that some of the CG is obviously AI-enhanced on the breast, and even the art style in the banner picture is not consistent. Nevertheless, the overall quality of the CG is still quite good and worth a fap. And there are a lot of gaping CG which I particularly like (and no censorship)
One thing worth noting is that the DLC scene for this game (DLC was included in the file) was head and shoulders better than the base game, so the sense at the first 3 hours of gameplay was worse than if you already beat the final boss in the post-game to view DLC scenes.
Thus, overall the CG is a 4/5
[As for which scene is DLC and which is the base game, refer to the DLSite page. You just need to know that CGs in the post-game is better]

The writing/script for the H scenes was terrible, but Niramare arguably has even worse writing. At least no line was used more than once for this game, while in Niramare, about 60% of the lines were reused in every single scene. But again, still terrible terrible writhing for the Hscene if compared to a real VN. The H scene script in the base game was particularly bad, whilst the DLC script was marginally better.
So H scene script is 3/5 as most RPGMs are bad with the H scene script as well.
The obvious shortcoming is the lack of depth, the plot is much shorter and flat.
But I am not sure if short and flat is a bad thing. IMO, a straightforward but enjoyable "short-length hentai fapping game" that made people horney whilst having some LMAO moments is far better than a much lengthy convoluted hentai game that barely gets people erect.
Overall, this may not be a great game, but it excels at what it is meant to be.
So I would agree it is similar to Niramare, but I would think they are basically neck on neck if not better than Niramare
If the translation was not made by crappy AI, I would at least give it a solid 4/5
