what did you do wrong?
well looked like you were burning too much E for no shot solutions. PuffPuff (whoever he is) passed up 2 maybe 3 kill shots at the start of the fight and then you tried shooting him 2-3 times when flipping about a little cheeky IMO!
you did a couple of things right like going vertical with the right timing to throw off PP's shot, always making him work for a shot. Of course you ended with a trademark debrody auger but if you smooth things out a little you will be getting there.
