The person who made that game obviously don't know what they're doing-- the sprites have too many colors to be an NES sprite (those only had max of 3).

That's very cool, but they could have made it a lot more authentic if they had the zombies run instead.

Yeah put it's still pretty damned cool for a one man job and a free download.

EDIT: One of my friends pointed out that Megaman's sprite has five colors. So you are wrong.

Mega Man is actually the exception to the rule (there's even one Mega Man boss sprite with 6 colors). Besides that though, sprites only have 4 colors.

-edit-

Ah, did a little more digging-- Mega Man uses two sprites (one for the head, one for the body), that's why they can have more colors.

If it had online play with 4 players I might care. But it doesn't, so I don't.
