I myself never played the original b/c I never had a NES. I did play an emulated version on a website and the game sucks in my opinion. But it's cool that they are finally adding classic, fan-loved characters. I mean who even knew who the ice-climbers were and they were added before Mac. And it appears he has a special damage bar. Above your normal damage bar he has a meter that fills up when he takes damage. Think of it as a super meter bar from your favorite fighting game. When it reaches max, your next attack will do extra damage. It's cool to see them trying new things.
