Ok, first of all I agree with the general opinion that this is fantastically well done. Specially for a early draft demo. Now on to the bugs there seems to be.
I too had issue with exiting out of the help menu. Also it seems that no matter what eye choice or angle, her eyes seem to always get flickers on them like there's a tv or something reflecting off of them. Also if you have the x-ray view on and it's just a penetration and hold scene instead of a motion shot - then their bodies wiggle around waiting for the next scene, but the x-ray penetration holds stationary which is a little disconcerting. That seems to be all that I've noticed, and besides the help menu exit is just nit-picking.
Very well done otherwise.
