A masterpiece in every facet: platforming, how the visuals and sound combine to create the alien planet of Zebes's dingy atmosphere, map design, and the high skill ceiling created by exploits both intentional and non-intentional. There's always a new sequence break or trick to learn every replay. And it's lovely to love a game that can be beaten in an afternoon when I need a fix.

The platforming takes getting used to at first, but once you do you won't miss a jump. Personally, Super Metroid's floatier controls immerse me more in the alien planet of Zebes, compared to Zero Mission's tighter platforming and maps.

I just wish the map had marked doors.
