Well, here are some preview images, MEGA links to Decals and a Demo of the new game.
Decals:

Demo:

Plot and gameplay wise, here's what I was able to understand from the FANZA page:
"Once again because of Nitori's defective inventions, Yuuka and a middle-aged man reeking of greed and lust are stuck in a distorted space where lust increase everytime you move. Will they be able to return to their original world?"
This is a bit like Amazon's previous game; Shipwrecked Spacecraft Todoroki where you have to go around and interact with stuff to solve puzzles.
I only got a groping, and that thing Kakashi does CG from the demo.
Just like his previous games, it's gonna be about to get main heroine horny to the max while unlocking events, huge breast milking, steamy sex, impregnation, you know the deal.
Edit: The Red Lever basically makes it so that you know which object should be interacted with, the easy to be exact and can't be changed once actived.
Once you go through a blue portal for the first time (Meaning you completed a level), Yuuka's horniness increase.
Only 2 levels are available in the Demo.
There's a handjob CG in the second level, and that's about it for the demo.
