First Game:
I really liked the Point and Click Adventure like controls here.
The room also just feels creepy, the projection of a random field with a chair, the radio, the empty book, the Face on the Computer Screen. Really great
Second Game:
The Photorealistic Background really adds a level of uneasyness, this becomes worse once you enter the other shack and take a look at the background there.
Also the way the protagonist moves is really unsettling.
I was scared to move to the next screen all the time
