This is a vampire game designed for the Text Adventure Literacy Jam. It's aimed towards beginners, and I think serves its purpose fairly well.
You begin outside a dark castle and have to find a way in. The tutorial will take you all the way through this part, about 1/10-1/5 of the game.
Inside, you have to explore the small castle and figure out a way to stop the vampire. There are quite a few items including red herrings, but everything is logical. I got stuck because I didn't notice one room exit at first.
There's not a ton of tension here. As a tutorial game, that's fine, and I've done the same in my own tutorial games, but I would wish for more in a bigger game. There's some nice atmospheric messages, though.
