Needs a fix as soon as possible.
Understanding that this is a demo, meaning that the game is published in order to be showcased to the players hence giving a taste of what the game is actually supposed to be - main mechanics, sound, visuals - definitely a bad demo. The frame rate drops at random moments, the hair on Sam's head appears and disappears randomly and the main issue - I can't continue after the barn section. I would assume Ethan follows us to the barn and we need to set-up something there (as a game developer, I know how things go), instead I am stuck with this: 
Hopefully game gets fixed.
Best of luck.
Edit: I forgot to say that I got stuck on the fence, while I was trying to make a shortcut to the barn - I replayed this section 3 times.
