Finished the game this weekend, really enjoyed the whole experience.
First of all, holy shit these graphics are amazing, probably the best looking game I've seen. And it runs great.
Regarding gameplay and story, It's not what I was expecting at first. It's more focused on story than on investigations - I imagined that further scenes will be more complex and have much bigger scope, however, that first murder scene turned out to be probably the most difficult one. That said, I wasn't disappointed, more like pleasantly surprised, because I found the story really captivating. I loved how the game sets the it's mood and ideas and plays around with them, everything fells really coherent.
The atmosphere is amazing, very melancholic, it feels that the time has stopped in this dying valley village. I very much enjoy exploring abandoned town/buildings, so this game was a treat for me.
The main complaint would be that sometimes the game is a bit too confusing about where player should go next. I appreciate that it doesn't hold your hand, but a few parts were just ridiculous, e.g. the part when I had to find a cave leading to the mine - I was lost in that area for a good 30 mins. Why didn't they use vision power to show where that hole was? And it's a hole, not a cave, the dialog was misleading.
Overall, I'd really recommend this game to play through during a lonely autumn evening. It took me only 3-4 hours, but the quality is easily worth the price. Imo short, but packed experience is better than a long stretched one.
