This mid-length IFComp 2015 game is an old-school game that is surprisingly forgiving. While you need to decipher passwords and complex machinery and examine each item and location, it has an internal consistency that makes it easier. Also, on two occasions when I was wandering around stuck, the game openly said "You remember that you..." and gave me the answer.
You are a vampire that seems like he would be played by a comedic actor in a darker film (kind of like a Buffy the Vampire take on an ancient Vampire). The game gets morbid but jokes as it does so (you remember torturing people a lot, for instance, but it' s played as an enjoyable hobby. I thought it was too much at a few points, but this game is unlikely to seriously offend anyone.
If you like puzzley games, you will love this one.
