We'll be adding a cinematic mode with scripted 3D camera choreography in the future. You'll be able to toggle between it and the game came in real-time during gameplay or in the gallery. You can check out some previews on our Redgifs (just search Eromancer Redgifs in google).
Regarding voices, right now we just have one voice volume slider. Breaking it down further isn't out of the question, if that's a feature people are interested in.
