The game content is way toned down from all the concept he posted way back at the beginning.
Can't stress over this enough, and it makes me sad.
Yeah, that makes me wanna cry
Eluku has pretty much said he's gonna go all out on this game, given the fact he's primarily a guro artist.
Problem is, I'm not exactly that convinced that he'll follow through, due to the fact that one of the earliest updates he made to the game was for one of the menu backgrounds.
Nona + catgirl on a horse type thing, with a tube connecting their anuses together.
Previously the tube was semi seethrough and they would, for lack of a better explanation, poop back and forth.
Then, not too long after, the tube would be completely opaque.
Reverting this change is probably the only conclusive way to know if he is going all the way, or limiting himself with the fetish content.
