8 bit Nintendo fighting sprites

[Phantom Killah]

Trying to sprite a tonne of Nintendo characters in a really simple 8bit fighting game type style. Mr. Frosty is done and Link is half done. I do not plan on making this into a game. MetaKnight's sword and Link's sword and shield are seperate sprites, which is why those characters excede the colour limit.

General idea of game (not important because game won't be made):

Every character has 3 attacks, a high, low, and special attack. Special attacks are usually ranged and have anywhere from 1 to 5 uses depending on the character, and the only way to recharge the special attack is to land a normal attack. (ie. if Link uses all of his arrows the only way to get more arrows is to get close and attack the enemy, he gets 1 more arrow use for every landed hit. Regular attacks are either strong, weak, or neutral, as are high and low blocks. So if your opponent has a weak high block it would be smart to use a character with a strong high attack. A strong block would decrease recieved damage by 90% where as a weak block would only decrease damage by 30%. There would be some kind of tag team system so that you'd pick two or three characters rather than one, allowing you to strategize.

But this is a sprite topic. Talk about the sprites.
