Eh, when I first started, I had no clue where to go once I got to Firelink Shrine. I played a little bit of Demon's Soul then decided I wanted to play some Dark Souls, so I knew the enemies were going to be hard and all. Kept trying to go through the graveyard.
If you get stuck, I'd say just look for the smallest bit of information to get you on the right path again, at the very least.
Getting through the game blind? Easy. There are a couple of places you might be going wtf, but other than that it's pretty straight forward. Getting 100% blind? Nope.
Well I dunno Photos, there was that one guy who did a good time on the Top Gear race track. I never would have expected that if somebody told me about it earlier, but I reckon that if a blind dude had a capable guide they could get through this game.
It'd be pretty f***ing tough in some places, I admit. Anor Londo's rafters...oh my word
