Super underrated but still flawed for sure. Probably the best thing is the atmosphere this game makes. There's such an eerie, claustrophobic feeling you get plunging deep into the caverns of an alien world, hunting for metroids that are gradually becoming stronger and more horrifying as you progress. And the ending sequence is incredibly cinematic and terrifying for a Game Boy game from 1991. But the fact that most rooms look exactly the same so you get lost easily and the somewhat clunky controls make it a bit hard to recommend. But if you can push through all that, this game is a great experience for any Metroid fan
