This could be a nice matching game, but it has a fatal flaw: there doesn't seem to be a re-shuffle when there are no more matches. That's why 18 defenders killed over 90 of my men, which by the way is also ridiculous - the archer took down each and every one of the men. A last thing that'd be nice to have are bonus items for matching more than 3, e.g. a way to get rid of those black balls or eliminating every ball of a certain color.
