Ecdysis

Ecdysis is a parser-based Lovecraftian horror game by Peter Nepstad, published in 2007. You're a man who wakes up at night to a pounding headache and weird visions. You get up and eat some pain medication, descend down the steps, feel strangely sweaty... and from there things only get more and more strange.

The game is very short - under 10 minutes long - so there isn't much else that can be said about it without spoilers. But in general, I think that the writing is descriptive and memorable, and the game definitely has a certain "shock" factor to it that makes it worth trying despite its brevity.

While the game world is rather linear and small, the implementation can get bizarrely detailed at times. The author gave the main character individual body parts like hands, feet, head, eyes and yes, even sweat, that have their own descriptions (Spoiler - click to show)that change as the adventure progresses because of... you know. There are also some non-standard verbs like "think" and an optional side quest where you put a blanket on one of the children. So, if you're the sort of player who likes searching for secrets and details in the game world, Ecdysis has some interesting things to find.

It should be noted that the game has a lot of glitches too, although to be fair, they don't hinder a regular playthrough at all. I guess you could think of them as just another "bonus feature" for the observant player. For instance, (Spoiler - click to show)you can make your own body parts fall off using the buggy "cover" verb. Try the command "cover me with eyes", for instance. A glitch like this suits the body horror aesthetic of the game surprisingly well, though.

Ecdysis is short and sweet. Well, maybe it's more sour and horrific than sweet, and its short length keeps it from being absolutely essential playing in my opinion, but it's an interesting title to try out if you have a bit of time and like parser-based horror.
