Incredibly acccomplished entry. From the very beggining you feel completely lost and intrigued with the story. The handling of audio is exceptionally well done, and it adds an extra layer of inmersion to the whole product. Graphically this is incredible as well: particles, light and shadows, focused and unfocused textures... there is an amazing amount of detail to it, and the fact that everything is customizable to a certain point on the graphic options of the menu just makes it even better.
Amazing work, overall. Would love to play an expanded version of it. Congratulations!
