Overall, the game is pretty good. I am personally not a Metroid fan, but the game is worth playing. My overall complaint with the game is the difficult controls. It takes a long time to master. The most frustrating controls are the speedboost and speedspark. I have watching many videos trying to master it and it is beyond frustrating. I cannot figure out how to get Samus to do the acrobatics before setting the speedspark. This is what is keeping me from giving the game a 5-star review.
