Pros and cons are down below) Check out my vid here:
Advantages:
1. I absolutely love that the game is based on existing legends - that is very cool. The game is entertaining, involving, scary and informative)
2. The spirit is scary - it's a very original mechanics of progressing the story and I love them. It takes several tries to understand the concept though (but that is a normal process of learning mechanics).
3. I loved the collectibles. They were not so hard to find and interesting to read about (though I rarely read additional collectible information)
Disadvantages:
1. I found a bug when the main character speaks that there is something behind the curtains when you haven't met the spirit yet (I played the game before some updates), maybe that is already fixed.
2. It's not clear under what conditions the ghost kills you. Maybe some hints in the pause menu would be a nice addition - that way they won't be burdening for those who like to figure everything out on their own but helpful for the others.
3. I didn't really liked the voice acting. I though it was a bit emotionless and bland - but that is my persona preference. I still think it's better than the lack of voice acting.
Overall:
I adored the concept and the demo! Can't wait for the full game. 5/5 in my list!
Hope my feedback was useful!
