There's not much to say, it's an excellent conversion of Super Mario World from SNES to GBA. It plays just as well and the only thing that makes it an inferior version compared to the original is that the audio quality is worse, the fact that the colors look very pale or that the field of view has been reduced, which has a solution because you can move the camera with the L button.
The things I like about this version is that it adds a list to see the status of the levels by pressing the select button on the world map, and the fact that you can play as Luigi, being a change of gameplay with respect to Mario.
What disappoints me and stops me from giving it a higher rating is the fact that it doesn't have that "deluxe" treatment that Super Mario Bros. on GBC or Super Mario 2 on GBA does, this port on the other hand comes without any add-ons, extra content, new mechanics or anything relevant new to highlight, which makes it a version that's only worth it if you play on a real GBA, because at the end of the day it's an inferior version to the original with nothing to really make up for it beyond portability. If you plan on playing Super Mario World on Switch or Wii U, you're better off going for the SNES version.
Conclusion
Despite being an inferior version to the original, it really is still a great way to experience Super Mario World, whether it's your first time playing it or you've played this game before, after all it's still Super Mario World, and it's one of the best platformers that's for sure.
