same deal, Metroid but with funky sprites and very little else. This one's not worth getting tho, if you want Metroid on GBA just get the remake, that also comes with this game as an unlockable

this game just did not age sorry

Honestly, the original Metroid is still really obtuse, and when Metroid: Zero Mission, a remake of this original Metroid title, is out, it'd be better to get that, since it also has the original Metroid as an unlockable if you beat Zero Mission.
