An interesting sprite animation, good dialog although it has to be said that I would have preferred it if it was voice acted. At the format the dialog is currently it has the feel that I'm slowly clicking through an RPG, not sure if that's a good thing.
I'm also not a fan of people submitting previews in this way either, I'm an old fashioned "The Portal is for finished pieces only" kinda guy, although I guess this is over three minutes long so exceptions can be made and I think this could just be me. I would have also made separate sprites for the close ups. At parts such as 00:32 and 00:45 the sprites become so pixelated that it's visually unpleasing.
Other then these little bits it's a good animation, great character movements with good touches such as one of the pumpkin guys falling over. I'll be keeping an eye out for the finished episode. One last thing might be to think of reducing the length of your ident at the beginning. 10 seconds is long enough, 22 seconds is far too long.
