30 hours to complete the game is awesome news.
I was really worried during the Kickstarter period that due to the limited budget it wouldn't be possible to create a game that long.
I do really wonder what has been the reason for removing the facial animations...
Not a satisfying result or new technology used?
If there's a longer trailer, I see no reason why it won't come public sooner or later, unless it's subject to NDA.
