Name that game.........?

Ok. These are the basic details. There was this game i played about ten years ago on either the snes or another system made at the time (not like the psx or nintendo 64, probably a less popular system). All i remember about it is that it was similar to (if not) metroid and that the first level was like a maze of a spaceship which has an open bottom that can easily be fallen through. It was also a platformer for the most part. It may have not been a large level but i remember being extremely frustrated at the difficulty of this game ( I was like, 6). It might be a vague description, but its all i have. Take several guesses if you want, first right answer = best answer.
