The concept is really cool but I had a lot of difficulty actually getting into the swing of it (pun intended). Never did pass the second level because the enemies were just too unforgiving. From what I could tell, intended behavior was that a solid hit with the flail would do more damage than a glancing blow, but it seemed like sometimes I hit an enemy with a real square blow but they didn't actually take damage from it, and other times I just kinda dragged the flail past them and it took off half their hit points.
With a bit of refinement this could be a super fun game though
