"Extremely horny, partially bisexual but primarily heterosexual monster porn" was not exactly on my bingo card going into this jam, but I am also not exactly complaining. For what this is trying to be, I thought it got the job done, though there were a few areas that could have made it shine a bit more.
Presentation was mostly solid across the board, though there were a few proofreading issues and at least one instance where "cashier" was written in the dialogue box instead of as a speaker tag. Music worked fine, and the sprites look really good. The TF looked decent despite the sketchiness (it's a jam, I get it) and Barry's yeen form looked really good as well. The oral CG looked kinda rough to me, though unfortunately I don't really know enough about art to articulate why; the penetration CG that followed looked better though.
Writing-wise, the sex scenes are clearly the focus here and I thought those were solid, even if Dorian's theatrics were a little much for me personally in the threesome route. The two places I thought this could have improved are in pacing leading up to and following the sex, and in setting up Clara's character.
In the comment below, Fuze notes both that Clara's witch angle is underutilized and that there should have been some additional post-coital denouement, and I wholeheartedly agree with both of these points.
I think we could have used some more introspection during the setup in the grocery store where we get a bit more about Clara's witchiness and her proclivities as a serial monsterfucker. We get hints of this during her conversation with Dorian later, but I didn't realize how porn focused the story (and Clara by extension) was until Clara made the comment "These panties are wet and not from the washing machine." which was way more forward than anything to that point and seemed like an abrupt tone shift to the horny.
I think having some more conversation between Clara and Barry at home could be a good vehicle for delivering more on Clara's backstory while simultaneously steadily ramping up the sexual tension instead of making that change so suddenly. There are also some unanswered questions, like Clara wondering why Barry is a were-gnoll, that maybe could have been more satisfyingly addressed either through this or that theoretical post-sex scene.
This does kinda stretch the premise of NovemBuck a little for me since the buck almost feels like a placeholder to get to the giant yeen, which feels more like the point of the VN, but eh, it's fine.
Ultimately, as a quick romp I think this was a really good effort and I hope to see more from you! (and will also check out the other VN that you apparently have!)
