Annoyed Undead is a short game written for I-Comp, a competition in which the game was not allowed to use an inventory. It would be interesting to see how far you can push the standard IF puzzle without requiring the PC to pick up any objects; but Annoyed Undead is altogether too short to really explore the possibilities.
You play a vampire who has awakened after 500 years, only to find that somebody has built a church right on top of his crypt. How dare they! The aim, then, is to escape from the church, and find some humans to kill in the process. This setting allows Roger Ostrander to implement the competition limitation in a neat way: there are portable objects in the game, but they are all too holy for you, a vampire, to pick up. You'll have to find some other way of transporting them.
Annoyed Undead is a simple puzzle game, which may serve as a short diversion. A walkthrough can be found here.
