Well, then here's more oldies:
256 again. I used to cop out on color selecting, now I just suck at it.
This was going to be on a cell phone game called Chess Boxing. It was never made for obvious gameplay reasons.
RPG makers all want sprites. Here's some I made on the FF4 scale, but they are original. Dig the crappy grass. I have an animated version somewhere. His feelers twich from time to time and the blood on his hand drips.
And lastly, one I made for a competition on a Game Maker forum. It had to be made from a template of a little man and only use 16 colors. I don't recall if I won. Another guy was going to make a headcrab zombie, but I beat him to the punch.
