Its got potential.
Not bad but you have alot of work to do. Try to make the players attacks faster. Controling the direction you are moving in mid flight or double jumps to change direction would be nice. Stunning the enemies with your melee attacks would be nice. Its very hard to keep your combos going. To many buttons for different actions, having the option of displaying what the keys do will help noobs out.
Other then that I like the graphics and after this game is fine tuned I think it will rock.
