Its a great Start.
Art Wise I thought it was cool, even tho the stance animation does not work.. aside from that I like the SHadowhedghog slide you gave him in his walk animation..
I liked all the moves , but thought they didn't transition well enough. tapping one button had the character launching into the air and doing all sorts of moves that didnt hit the enemy.. you should have more direct input for those types of moves, and simply give the player better -chainable- attacks. and allow the player the choice to launch the enemy if he wants..
aside from that the rest is great.. the launched grappling blade move was good to, reminded me of my Alloy game :)
keep up the good work can wait to see more..
