I think if you keep at it, you can make this mod interesting. I just think the sprites and items could use some changes, you gotta keep them in the same style as terraria as a whole. But with that, I was a little bored and took a shot at 'fixing' some sprites. What do you think?
Edit - Seems you cant drag and download the sprites. If you want, you can download them in that little .zip down there.
