A really solid AVN! I'm not into everything this AVN threw at me & appreciated how easily I could close unwanted romantic routes, and how gracefully the you executed said decisions within the story. Lucy & Grace are my fav character designs, as thet consistently look great regardless of the lighting conditions.
As an animator, I only have 1 piece of constructive feedback, some animations look robotic, like limbs/torso/hip joints haven't been animated. (Example: Lucy on top near the end of Ch.13, was particularly jarring. Happy to offer a couple quick tips to minimize animation workload & increase quality, if you want.)
Outside of that, it's really solid & only sticks out because of how good the rest of your AVN is. I'll definitely follow Zargon_Games and look forward to any future updates.
