Maybe for a 5 hours long game you won't be willing to pay 19€, but for 10€ it's worth every cent, even though it's among the shortest games I've played.
If I have to categorize this game I'd say this is a lovecraftian game, it's a detective story with paranormal and horror features all perfectly encased in the most beautiful and realistic environment ever seen in a videogame, not to mention the absolutely perfect music that will give you goose bumps.
***GAMEPLAY 8/10: Investigative, slow paced. You won't be running around guns blazing in this game, you have to look for hints or you'll be missing something for sure. You can complete everything or nothing in any order. You won't see any kind of log book, map or quest marker. I really liked it, but unfortunately the game is a bit too short to enjoy the investigative experience. Another great thing about the gameplay is that you will never experience any interruption because the game needs to load areas, you start from the beginning and reach the end in one single walk. This is probably the reason why this game is so short, a longer and a bigger game environment might have required a loading screen or two.
***STORY 8/10: That's all this game is about, story. As you are told at the beginning of the game "This game is a narrative experience that does not hold your hand". Step by step you'll discover the truth about the mysterious events that happened in Red Creek Valley until you reach the end where the ultimate truth will be revealed. I can't tell anything without spoiling something, so I'll just say it's really enjoyable.
***GRAPHICS 10/10: I have never, NEVER, seen such beautiful environment. I grew up near the Alps and I can see that exact scenery in this game; rocks, trees, bushes, and even the undergrowth look absolutely real. The textures are high quality photos of actual, real life environment. I suggest you read this to learn more about this spectacular creation. http://www.theastronauts.com/2014/03/visual-revolution-vanishing-ethan-carter/
***SOUND 9/10: Beautiful music completes the game, it goes hand in hand with the environment. I could stay hours looking at the landscape listening to the music... and maybe i did.
Overall score 9/10
Grab it when it's around 10€, you won't regret it.
