I've just played a couple Battles, and I have to say they are some of the most fun and different open-ended (staying the same character, same weapon, no weak points, just attack it strategically) boss fights I've played. Trying to get the boss to destroy the columns so I can use the heavy stones to kill him, picking up the maces of dead enemies to throw at him, and dodging arrows.
This game is really amazing, though. The graphics and animations are stunning, combat is smooth and isn't generic and can change up quite often with ranged weapons and physics objects.
Btw, do the morningstar maces that the wolfs drop do more damage than your starter sword? And lastly: I couldn't help but think that I was killing furries in this game.
