Wow. A little creppy, yes, but cool nonetheless. The beginning had me puzzled, but I figured it out. I like the way you used him talking into a tape recorder as a suicide note. I don't think the characters are as deep as they could be, but you said this was based off an RP, so I guess you knew them in your mind. But a little background for the reader wouldn't hurt.
Overall, it's very good.
