Amazing experience. Disgustingly difficult, but that's exactly what I loved the most. It's not hard to get to the credits, but the thing is, the real game begins after that. And it's been a long time since a game has put me on edge so many times, this is really one of the hardest games I've ever played, but in a good way. When Nintendo feels like it, they're godlike at making insanely difficult post-game challenges and here they REALLY felt like it. I 100%'d the game and enjoyed every second of it.

I also loved the characterisation done in the enemy and treasure logs, for both Olimar and Louie. Louie you crazy bastard.
