I finally got a chance to play SMG and within a day, I had 32 stars.
Didja finally get your Wii? Didja? ^_^
I'm taking the slow and savoring route with Galaxy. I only have about seven stars so far, but I've replayed the few levels I already beat numerous times. Not that there's a whole lot of of other secrets to be found, but at least I'll have a nice surplus of Star Bits by the end. :)
And I just discovered that "secret move" that the instruction manual and even the guide failed to mention; the "homing stomp," which is accomplished by pressing the Z button at the peak of a midair spin. Very cool.
