This is an amazing remake that improves upon every aspect from the original Metroid game on the NES. Not only that, it also adds the trademark unsettling horror-esque elements into this game.
The Zero-Suit segment while seeming tedious, personally made me feel anxiety-ridden, showing just how helpless you are without the suit.
The boss fights are pretty fast, the soundtrack is good, and the gameplay is pretty fun and I often found myself hardly getting lost or frustrated on where to go in the game as it does a good job of guiding you in a subtle way.
