Thanks for the nice update. :)
I recently started toying with your tileset. I feel some attack animations look a bit weird(especially skeleton and goblin). I think it's because their last frame is the same as the first frame of idle animations.

Here's a small online demo I just made. Feel free to try it out.
(Arrow keys to move around and you can attack by bumping, 1/2 keys to change creature, 3/4 keys to change faction)
I set the animation 1/8 seconds for each frame. (one cycle in 0.5 seconds)
1/12 seconds for walking though.
Also about the devil, I know he teleports, but it would be nice if there was an walk animation too.
By the way, do you have any plans for making dungeons or underground tiles?
