Awesome!
Squiggly fish (trouter) and Lakidu (the cloud fucker who throw spiny eggs at Mario) are by far the most underrated of all Mario antagonists. Finally, the spotlight has been thrusted onto this great character (much to the dismay of Goombas everywhere).
Seriously, love the game, love the secret stuff, LOVE the music (T&C fo' life), and the controls weren't that bad. For everyone who can't figure it out... use your left hand's middle finger to hit the "A" key, use your right hand's index finger to hit the "D" key, and use your left hand's index finger to hit "S" and "W". It saves your wrists from carpal tunnel syndrome. Great game!
