I just backed the kickstarter and thought that i should try making a small animation.
The sprites are from Super Mario Bros 3 and are not made by me. However, the animation is 🙂 Let me know if you want the BMPs (and what the background color should be).
Nice work! I usually prefer black backgrounds because black pixels are “off,” which allows more attention to be drawn to the artwork. It’s a matter of personal preference though. Some sprites just don’t look right on a black background, so I sometimes outline them in a very dark gray.
