Great game. The first Metroid game I played all the way through, and I really enjoyed it, but it was very easy to get lost and hit dead ends, and not having the ability to fast travel makes it a bit annoying when you have to backtrack long distances, but other than those minor things, my only real issue with the game is the map. Something that Zero Mission fixed was that it didn't show where doors are and there were several one way paths, so even when I knew where I wanted to go and had had the whole map filled out, I would still have trouble finding my way to things. Still overall a great game
