This game is a prequel to the “Dracula: Love Kills” (although “Love Kills” start contradicts the “Origin's” ending).
“Dracula: Origin” has a rather beautiful design and interesting story with some nice variations of the classic Stoker's novel, although I felt a bit bored in the beginning and, at one point, thought of quitting the game completely.
As to the puzzles, they are either too simple, or too difficult and rely heavily on trial and error and dialogue re-reading, which I personally found unconventional and inconvenient.
Also, it's easy to miss items, leading you to often re-visiting of the same spots and circling around, moving the cursor carefully across the screen.
As many of the puzzles do not follow a straightforward one path logic or any logic at all, this walkthough guide is highly recommended to save time and avoid frustration: http://www.gameboomers.com/wtcheats/pcDd/draculaorigin.htm
I played it for the story anyway. Not the best puzzles and clues in the genre.
My overall rating: 6/10. The sequel is much better.
