good start
ok, i liked what you have ere and thats why this is going to be so harsh, if it was crap i would have just said, this is crap and moved on, but heres what i think could be improved/ problems i found:
1) put in a block, I kept getting killed by the first brown guy, who would just hold his sword out and everytime i tried to hit him, i got killed,
2) i liked the different stances, but they should have different attacks,
3) there should be more moves in general, try doing seperate low & high or something.
Again, not trying to be a dick, just suggestions for the next time aound
