From what I understand this was named "New York Nyankees" in Japan due to it being set, mostly, in New York and nyan being Japanese onomatopoeia for the sound a cat makes.
Was beating the final boss a second time all that necessary if it doesn't give you anything different like a different ending? They should have taken that second final boss fight out of the game since it didn't serve any purpose to be honest. This game was also featured on Nick Arcade back in the day.
Seems to me like they wanted a "hard mode" perhaps, since you don't have any items/weapons at that time... but then again, they could've just done an NG+ mode, or at least have a longer ending.
32:39, WILLY DON'T GRAB KONG'S WILLY, IT'S A KID'S GAME GODDAMMIT. Seriously, this game is AWESOME. I rented it after seeing it in Nintendo Power and beat it for the couple of days we had rented it. SO good.
