Just in time for Halloween, you can switch out your Steam avatar to one of these Emily Wants to Play characters. I included the new characters also.
Here is a link to the avatars:

Have fun :)
Oh, also... Some people have asked how to download the demo. It is on the main Emily Wants to Play Too store page, over on the right side, theres a "Download Demo" button.
