not very entertaining
The games movement control method is perfect, everything is quick and easy to control, however i believe that more effort could have been put into the combos and specials, there should also be special finishing moves, something unexpected but goes along with each character, it also needs taunts to throw the player off so that it will make everyone who plays this game, want to play it a second time.
other than that, everything else is fine, the music, graphics, characters, and levels were all good.
more move options are all that's needed.
i would suggest one of them to be a downward stab, as cheesy as it is, there is always satisfaction in running blades through your oponents head.
oh and you should add blood here and there, just doesnt seem rite to have a sword fighting game without bloodshed.
