How to play Bullet Witch

Triserpent was a long fight but you know what? it was still a great final boss, i men maybe my perceptions were being colored by my last two games beaten being Soul Calibur 5 and Mass Effect 3, which both lacked a final boss and thus closure, but every time i have taken him on it felt like a legit good time and never annoyed me, unlike that jerk Dragobat from the plane level,

But for real this game should never have costed 60$ probably could have thrived as a 10$ downloadable game with marketing centered on how different it is from other 3ps's
