It's weird that this is a straight remake of Metroid 2 because it feels like a fangame. Not that that's a bad thing, but the linearity of the areas and all the bosses being recycled makes this feel unofficial despite that being what Metroid 2 is actually like. The goal of this game was to bring Metroid 2 up to the style of Zero Mission and Fusion, and it definitely succeeds there. The graphics, music, and gameplay are all exactly up to those standards.
