This was originally just a test to see if I could make all four characters use the same Genesis/Megadrive palette*. I believe I succeeded at that, but I think I could make the sprites better. Now I would like to make larger sprites, but with just Sonic and Amy (less work, and more colors to go around), but first I would like to learn what I can from these.
*15 colors from 9 bit RGB, plus transparency.
