I didn't play this game back in the Game Boy days and it is pretty rough to play today on the Switch's emulator. It's no wonder we've gotten both a great official and unofficial remake for it. I shouldn't be too hard on it though. It was doing some cool stuff for the Game Boy. It feels pretty atmospheric with some interesting music and you do feel like you're descending into this scary alien planet. Unfortunately, the lack of map and all the environments looking very similar (especially when it never got a colour version for the GBC) make it incredibly difficult to navigate. I know getting lost can sometimes be the point of these games but when you can't discern one area from another, it just becomes a frustrating experience. I did still get some enjoyment from hunting down all the metroids despite the repetition. I'm glad to have played through it but any revisit will be through either of the remakes.
