Cool
HOORAY FOR Nintendo! I hope you make part 2.
GRAP: I thought the graphics, except on Kung Fu (;p), were pretty cool. Although I thought Mario looked strange...or maybe Mario just kept gettin' peeved all the time. The goombas on fire were cool XD
HUMOR: The nonstalgic punching noise is pounch-Out, Kung-Fu ("The BLINDING Pain!!!") and the flaming goombas were great.
Violence: Nothing bad here
Sound: Nolsalgia, and good music (again with the punching sounds); I liked Legend of Zelda and Punch Out.
MORE NES COLLAB!
Maybe you should've added another again, maybe.
MEGAMAN!!! Or maybe Guardian Legend? Or Anticipation? Or Ninja GAiden?
