for the peitho path, i found a few options when mashing keys.
d makes a coughing sound but I'm unsure what exactly it does, maybe deep-throat?
c makes the person using you cum, and ends the scene, opening up the terminal for 'improvement' in the bedroom.
after adding some improvements i can see more of the body, so I'm assuming that there's a texture glitch or bug in the release that's preventing the character texture, aside from the new improvements, from showing.
The good news, all the new improvements are visible, once you get them, and they can help you see your character outline better. in the first scene you'll have to rely on the animated sweat droplets and drool lines similar to those in deep throat simulator in order to see.
to see them move your mouse back and forward on the screen.
Also, after much experimentation and finally finishing the scene with the cum button, I have found that the dick is on the right side of the screen. i have not confirmed its vertical position and it is possible to lose it completely and never find it again.
thus ends my notes, hope it helps some people.
