As I've said I'm very busy with my own project, but I'm always there for programming advice and help, even contributing if I have the time, but that is uncertain. I'm also in for testing, I've been testing my own stuff for quite a while, and I'm pretty critical.
Also with the character sprites, do you aim for the same visualization as in the original? Because there, they didn't draw the characters from hand, they modeled and pre-rendered them into several bits and pieces, otherwise you're stuck with a motherlode of textures to manage. This is done for each animation and their frames, from each possible angle.
