I really like the art on this. It was great to look at and added alot to the character overall. I also liked the animation on the sword swing, it is very subtle but adds to the effect. The art is cute and fun!
One thing that may help gameplay is to limit the distance the sword can travel from the character. This could push a player to need to move the character instead of only the sword.
In all, I really liked the entry. Good job!
