Just caught up on your work so far on wiki, looks great! (Granted i don't know unity and all that so this may just be simple stuff lol)
It's late where i am, but i'll try and get around to watching this video conference tomorrow, so i don't ask a bunch of the same questions and whatnot, but i love this kind of stuff so i'll be excited to hear more about it.
I don't know how much of a FLOSS purist you are, but we do have a Discord channel (a few people with skills in the area are getting a FLOSS alternative going, Matrix (Software) i think it was?) if you are interested. We have a text channel for the game project with some discussion/related links so far, but i can take screenshots, or annotate that on a page or something if need be.
(Sidenote, i don't know what hardware you have, but Tilt Brush is now open source, so you can load that up and mess around if you haven't already !
