ONE THING
There was just one thing that completely ruined this game. The enemies, the enemies can hit you while they are on the ground while you are IN THE AIR. For example, say I jump and do an attack on one of the ninjas below me, and bring it up into the air and keep going, then his little pal calms up behind me while I am still IN THE AIR and while it is ON THE GROUND it swung it's sword, HIT ME, FOR NO REASON, WHILE I WAS IN THE AIR, WHERE I SHOULD HAVE BEEN OUT OF REACH and sent me to the ground, then that leads to another thing, with an enemy on each of my side I was stuck in an endless attack by my opponents where they just knocked me back and forth between them before I died.
