Breeders of the Nephelym is an immersive, beautifully erotic 3D adventure game centered around catching and breeding the Nephelym, an enigmatic race of monster-human hybrids.
There are no loading screens at all, no annoying cutscenes, and the camera was programmed from the ground up to be a seamless smooth transition between every mode. Features were added to increase control over your breeder--you can at any time remove all or particular pieces of clothing. You have control over the different phases of any sex scene, and complete freedom with camera movement and speed.
And yes, breasts, butts, and even the belly will bounce during animations!
To further immersion more, graphical beauty is a priority. Lighting is high quality and lots of foliage is used. I realize this comes with steeper hardware requirements than your average hentai game, so I have tried to optimize where possible, and it will be possible to scale down rendering quality if needed.
Further on the quest for highest quality hentai game, I went all out and implemented a customized industry-grade fur system.
