Fantastic design. Very much creative!
I think you've got some good concepts down, and some great ideas in your head for things to come. But, at the same time, there's a lot you can do to make it even better. I suggest you listen to AoDC and try to get this project online, if you feel you can. I think having a single-player mode that sort of plays like Four Swords Adventures (with levels, if you will) could work nicely. That's about all I have to say. Awesome work, keep it up.
Also, I'm so Red Link.
