Very good premise for a game and an excellent style! Unfortunately, I found the sigil right away so it ended up not needing to look at any of the other objects in the room, although reading the other comments I think I might have gotten lucky. I do however, think it would have been a little more interesting to not have been told what entity we were looking for and have the player suss it out themselves with the context clues in the room, but this is a very promising start if it were to be expanded out into a longer and larger game.
