You can do Motion Caüturing via VR-Trackers? I did not know that. This sounds awesome! Since we are at that topic now, from 0 to 10, how possible would be a VR-Version with Fen swallowing and digesting us in first person. Now that would be a dream becoming true!
When not planned in this versuon of the game, maybe as a sequel after you are finished with this one! People would pay extra for that! (I would).
