the entire track has a much floatier, spacey feel to it. yet the bell-ish sound grounds it; adds the "garden" sound to the song. quite lighter than my own mix, haha.
RE: game music. yeah, guilty. I can't help but think of Super Mario Galaxy while listening to this. It has that feel to it.
the only thing I'd change is the synth that comes in at 2:19, and only barely (the phaser sounds a bit strong).
