I remember on Minecraft on the PC, a couple of years ago I'd play this games or quests, whatever you'd call them, for example Amnesia Minecraft. It had to be something with the name "Journey" in it or "Nether" and it isn't from Minecraft Story Mode. It started off the game by waking up in this big room and walking around this huge house, and being greeted by this guy named Sebastian in the game, then you leave the house and you're locked out of it, and there's all this greenery around, like a house in the woods or something, if anyone knows what its called? I've been trying to find the gameplay online.
Added (1). It was an adventure map, and when you first started the game it was in a white room.
