Since all my other characters are cartoon-y I decided to give the player character an appropriate update.  There are not many pixels to work with for expressive features so I figured it'd be funny if his head ballooned out.  Now I'm thinking it might be cool if other body parts could do the same in Battletoads-/Darkstalker's Victor-style.

Also I kinda broke NES rules but not really.  Overlapping sprites like these were done in TMNT3.
