The game is Metroid Zero Mission, this is the first time I beat a Metroid game, so I decided to start with this one.
I should mention that I used save states and rewind to get the hardest items, but hey, I don’t have the time to master all the games I play ¯_(ツ)_/¯
Why isn’t the best one?
I didn’t play the others to say it for myself. People have said exploration is more organic on the other games of the series.
I liked the gameplay but I disliked the mechanic of having to beat an arbitrary amount of bosses to unlock the next area.
