Haha yea the last phase is even hard for me, the jump in difficulty might be a tad too much. There seems to be a pattern among players (comments here some friends play testing it) to not use melee so I'll definitely have to think how I can encourage it's use. A lot of the mechanics (doing combos etc) revolve around it's use so it's definitely not intended. I think just having more clear openings, where the boss is idle, could make it feel more safe to use. Thanks for playing!
