There are some spoiler free guides on youtube, they allude to some secrets without spoiling the game. I watched one a long time ago and it made the game open up alot more. There is so much in the game i doubt we will ever get any more hints or anything like that in the game until 1.0 and even then i wouldn't be surprised if there wasn't. It feels like the game enourages the old internet days of forums and stuff of people trying to figure out secrets in games together before everything was uploaded to youtube. Lol
