I like the over all concept and the simplicity of it all. I did not quite get the feeling that the dwarfs are afraid of the enemies as it look like they would fight regardless...maybe I saw it wrong. I would've like to been able to better gauge how many hits both my dwarfs and the enemies could take as it made the levels with more enemies harder to know if I was doing well.
For example, I would kill 6 out 8 foxes and still have my 4-5 dwarfs but when I lure one wolf it one shot kill my dwarfs and it was not fun because I could not understand why they suddenly die. That's really my only recommendation...maybe add a way to tell the player health to strategize better. :) Still, this is a solid an well design game. :D
