The larger sprite makes Samus easier to see,
especially against the dark background, but it also makes the screen feel more cramped, and it's hard to get a grasp on what's around you.
I know that the light coloured text does not stand out
especially well
against background, but I purposely did not use a
darker colour because this took away from the lightness (in both appearance and — more importantly — «feel») of the cover.
