Crazy Kong was the first kill screen I ever achieved in any Kong variant, and I gotta tell ya, the moment and the buildup to it was the most satisfying, the most exciting, and the most fun of any of them. I downloaded it when I was heavy into my DK training phase, gave it a shot and said "OK, I'm giving myself an ultimatum: kill screen this in 24 hours!" It took me 36. I underestimated it. It came down to me staying up all night, going into a (pardon the pun) crazed state until laying the final smackdown at 4 AM.
DK Japan snuck up on me when I wasn't expecting it, DK MAME was more like "meh, finally," and my first DK arcade kill screen was in public, so that was cool, but none of it was as good as CK. I was so, so excited and pumped. I let out a roar of victory.
And I can't stop loving the game. It's just so shitty and ridiculous.
