Great for a first version
First of GREAT WORK MAN! I see how much effort you put in this and I see why you are frustrated by those people giving you a bad score, just ignore them! As you say your selves they are probably not over 12 or so... Things i noticed: Your drawing skill has increased a lot! I mean the background was so great! The animation was fluent and everything, even if there are some minor things to change e.g.: if you do a combo or something like that you stand still for like two or three seconds which gives your opponents time to attack, but well its the first version so i'm sure that your going to fix that. of course there are the glitches, but there are glitches in every game in the beginning.
Points why i give you a 10 :
The animation was flawless
The background and story-line pics were great and added to the atmosphere
Many nice moves and combos added like running up the wall etc. ^^ luv to kill my opponents in the air :-3
You could steal the opponents weapon and fight dual wielding which is totally awesome!
All the work and time you dedicated to this piece of work already deserves a 10 anyways!
Continue doing what your doing and don't listen to all those jkhfgaslfgl ^^
