Well, this is a fairly difficult task you're setting up, and I'm not exactly a skilled spriter, You could use the sprite I made as a base for you to experiment with, or you could use it. I am, however, uncertain as to how I could make this. In any case, you can use the sprite however you want, the left-right thing wasn't fully done, I was thinking of making it more cubic, giving it a top to make it more 3d, but as it is, it could potentially work for a side scroller.
