I've heard good things about Nosferatu: The Wrath of Malachi, it's a randomized horror game that I see mentioned every once in a while in cult horror game circles. People say it's a good adaption of the classic vampire movie its based on, and like the movie, is a niche but quality work in the vampire genre. Nosferatu is the only vampire that has creeped me out, so that's a good sign for me.
But as a heads-up, I also am aware the voice acting in this game is pretty bad, and I hear there's no graphics options, and a few bugs (but not new ones, the old game was kind of buggy). Also the game is known to be kind of difficult, but with good atmosphere.
The developers say this on their forums for keys from the Indie Gala bundles:
"Please note Kiss Ltd were not responsible for any previous bundle that may have contained this game.
We are looking for who ran the previous bundle and will be happy to give them a batch of keys to route to all their customers who bought that bundle, but we cannot manage individual requests for keys.
We will advise you when we know more."
