As I said before, everything else is polished to a mirror shine. The graphics are amazing, and the art design is even better; every single level is a treat for the eyes, even the background on some galaxies like the Toy Time Galaxy (one of my personal favorites). It runs just as well in 16:9 and 480p; unlike other titles like Twilight Princess, which was prone to jaggies, Galaxy looks amazing from start to finish. The music is also absolutely top-notch; much of it is orchestrated, and some tunes, like the theme for the Bowser levels, will have you replaying some galaxies just to hear the music again.
Normally, this is the part of the review where I list the things that Galaxy does wrong, but I’m honestly coming up short. This game has a distinct goal in mind, and it accomplishes it with gusto. I could point out some minor details, such as the difficulty I had trying to jump out of water, or how Peach’s voice is a little annoying in the intro, but I would be redefining the word "nitpicking". As cliché as it may be, I can’t think of anything bad to say about Galaxy.
[ADDENDUM (2/9/08): Upon playing through the game 100%, there is one problem that does stand out, and that’s the bosses. Some of these bosses are highly clever, such as the Megaleg seen in E3 videos, but others mostly involve flinging an enemy’s projectiles back at them. Bosses are also reused a fair amount, especially the boss battles of domes, to the point where I think they could have done better, especially given the variety in the levels.]
