I love that game. Personally, I prefer the Genesis one, but it's still pretty good.
Here's some stuff I did today:
One of them is a UI button that contains several icons I made, one is the final-ish version of my game's current protagonist sprite. I'll probably touch it up, as it only contains 4/12 colors (normal+overlay), but right now it's sitting pretty. I included the full-resolution sword, though there's a scaled down version on the shield icon in the UI element.
