I was a bit confused at first about where the new content was, because I didn't notice the new "pull out" button in the corner during the glory hole scene. Admittedly the monochrome color palette doesn't really give all that many ways of drawing attention to it, but you might want to look into presenting choices in a different way than an extra button next to the "press here to continue" players have been clicking the whole time.
The QTE was also pretty puzzling to me (though I'm apparently not the first to mention this), since I didn't realize you still had to click the "press here to continue" button for your click to register.
