This is the best 2D Metroid right? It feels objectively the most polished, the most fun, the most epic, the most bad ass. I now need to replay all the others just to be sure, but goddamn. Take all the best components from every other game in the series, filter out any filler or extraneous bits, make some tasteful additions and polishes here and there. Bada bing bada boom, you got yourself a stew going.
