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)_/¯
I really took my time didn’t I?
I loved to back track on my own (when I was not lost).
