I liked...
The style of the game overall. I think a lot can be done to this to make it more interesting. One thing, and I know it's cliche, but is you can make a special attack system, where as you build up enough energy and unleash it on the enemy. I think the whole fighting sequence was hard, but hey, challenges are good. All in all, you have good potential, and give this piece a bit of work, like adding a story and such to it, and you could get a great game.
