The demo is a lot better than I tought it would be. I've backed this game with not big expectations, to support the adventure genre, and now I'm eagerly waiting for the release of this first episode. Sad I've didn't pledged more to this project, who actually deserved it.
For my thoughts about the demo :
The voice acting and music is perfect, very immersive.
The animation is not perfect, but in the vein of Telltale's Walking Dead (who had a bigger budget). But the story and the sounds are so immersive that it didn't bothered me at all (which I thought it would, seeing the screenshots).
I loved the visual of the angel statue a lot, and the visual in general. I've been stressed the entire demo, feeling the urge to move, to resolve the case as fast as I could to save Erica's brother.
So, for me, it's a great job. Great story, ambiance, voices, puzzles...
