Nevermore is a loose adaptation of Edgar Allan Poe's poem The Raven. You assume the role of a sad, drug-addled alchemist who seeks to resurrect his lost love Lenore, whose life was claimed by one of his own misguided experiments. The text is moody enough, and the drug-use mechanics are a great touch. However, the game is hamstrung by some convoluted puzzles with vague hints (the alchemical process is inscrutable, and I believe it is possible to lock the game in an unwinnable state by using an item in a certain way before you are done with it). If you enjoy horror IF (particularly Poe and Lovecraft), Nevermore is worth a shot; but don't feel too guilty about using the game's built-in hint system or even resorting to a walkthrough.
