This map has a slightly bigger main platform, but the real game-changers are the platforms. The real star of the Galvan Maps is Galvan Prime. Though they aren't moving in all sorts of directions, they can still be a challenge because in the heat of battle, if you misjudge the distance between you and the moving platform then you could be opening yourself to a world of hurt. At random moments throughout your fierce battles, the two floating platforms will move of their own accord.
Small Galvan Prime is just one main platform accompanied by two floating ones.
