I always have a hard time rating some of these "mix random stuff to get lewd results" games since they always boil down to "AA, AB, AC, AD, BA, BB, BC" and so on. This one's got a couple secrets to it, which is nice, I guess, one secret makes the 9 ingredients more powerful, the other secret shows you how you got those 9 ingredients, though I'm kinda annoyed that some of the scenes tied to them aren't actually relevant, like the rabbit one being about muscle growth for some reason.
The latter secret is only accessible if you've made about half of the game's combinations though, so the game digs right into one of my pet peeves with these kinds of games, where you're forced into doing a bunch of stuff you might not like, just to see the rest of the content.

Anyway, uh, the AI art in the game is... mostly serviceable, though the dev couldn't figure out how to get some of the tails to work in the AI so the dev kinda hamfisted it like "haha her tail is SUPPOSED to look like that, lol!". I think the worst AI-appearance-wise is probably the mermaid stuff, since the AI simply can't figure out where the fins are supposed to go, ha. Realtalk I would've tossed the mermaid one out for something else entirely, maybe another animal, or a WG one, IDK. I thought the plump peach would've been WG, but it's butt expansion, most of the WG is behind the milk.
