This is like a SNES version of the NES Metroid, with the consequently better (and bigger) graphics and music.
Due to how the game tracks time, the in-game completion time is 30 minutes (2 minutes better than the previous version).
Items collected: 27% (1% more than the previous version).
Note: This video skips the intro sequence using a save slot. That shortens the movie file by about 2 minutes, but it has no effect to the completion time reported by the game.
