So I haven't played this for a while, judging from old saves (which have a >95% chance of being broken) I played between 0.6.1-0.8.0. For the longest time I wasn't sure when I wanted to try again, but it'll either be right now, or when tentacles that can parasite/impregnate you are added. Actually, can the small ones parasite already? When/how long til that's added?
Now, about the art. I've thought about this for a while, not a big fan of most of the current art, and the older art had something about it. Not entirely sure anymore with which art belongs to who, and which is a combination effort. The style of the art currently in the game is mostly too... Chibi? Like for example the artwork of Anya shared on page 34 just looks off. SUPER chubby face, and the arms look very disproportionate compared to her hands. Preview images in the OP too, GuestAnim the face looks very awkward and the body looks too "stiff", as in, there's too many angles, hardly any curves. Why does her vaginal area look like it's raised, and why is her right side of that area (seen on the left) got a little triangular bit? Leg in the air's knee also looks broken as fuck, either the knee is pointed to hell and back, or the knee cap is just not there. School2 the face's eyes seem too huge (gives a chibi effect) and the tits seem like they're lifted by a high push up bra, which might be intentional when I look at PregState2 and it doesn't have that issue, but then the underwear only version in the banner doesn't have that same push up effect... Is this a case of shirt-too-small? Paizuri looks REALLY good, and then Carla kinda is the reverse of the chibi effect, eyes not too large but the body looks weird. I also noticed, the arms in PS2 look too long, but only because a natural stance in the real word doesn't have the arm sit perfectly straight, it's always bent a tiny bit. ImpBirthScene looks mostly ok, mostly eye-slightly-too-big syndrome but doesn't look chibi like the other stuff mentioned so far. Stats is REALLY old so I'm not gonna even mention it, actually fuck it I will, may as well, the facial features look off, like half her face is facing directly forward, toward us and the other half is facing directly foward, same as her body. Mostly caused by the eyes. Don't think I need to mention anything else.
Sorry other artist for my criticism!
Most of the older stuff was absolutely in need of an update don't get me wrong, but one of the images I liked the best was the old forward-facing standing CG, especially when fully pregnant, regardless of clothed or nude state.
