Wow, so many great guesses. No one has it yet, though. I'll give a mini clue before I move on to clue 2 and let everyone know that this is not a primarily scary game, although there may be one part that's somewhat creepy, depending on your creep meter.
Clue 2: This is a most unusual way to send a person messages. Though I have to make sure I send the right things in the right order to get my intended message across.
