I'm about 4 hours in and i feel like i'm just getting the hang on the gameplay. I like the managing your backpack so you don't fall over and figuring out the best route to your destination.
That said i'm on Normal and i've yet to be caught by BTs. The sensor always blinks in the direction of a BT so it's pretty easy to circumnavigate those sections(maybe it gets harder further into the game). I do love throwing piss/poo/sweat grenades at BTs.
