Grue.

This game was fun and clever; I think a large chunk of judges found the concept fun and original.

You are a lurking grue, and you have to devour an adventurer.

Because it is completely dark, you have rely on your other senses.

I had difficulty getting helpful responses from going in different directions, and with the final verb.

Overall, if the feedback from comp judges is implemented, this would be a game that continues to get played for a long time.
