Finally.
The premise, credits and download links are here:

There are plenty of mirrors and even a torrent download option. There is a .zip and a .rar option as well. The .zip is double zipped so if you don't know how to open that just get the .rar.
I look forward to everyone playing it. I've been working on it on and off for a year so I'm anxious to hear your comments.
Thanks!
EDIT: When you hear the little girl whisper, "Saaaave me..." Do yourself a favor and save. :)
