Big improvement on the first game. The power-ups were so much more fun and actually felt like getting stronger. The quest to destroy all the Metroids was a fun way to change the structure of the game. I used maps online for most of my playtime which obviously changes the way I played the game, but I felt it necessary to improve my experience. The refill points for pickups were so much better than having to grind for health and missiles. Wasn't expecting to enjoy the game as much as I did.
