I have beaten Metroid and other similar games. This is by far the most frustrating game I have ever played. It is nearly impossible to get past simple parts of the game. It really doesn't matter how you time your attack. You can do the same thing 2x in and get two different results. I have only played the game for about 8 hours total, but I am done with it. It might be worth the effort if the game itself was better. However, it just isn't cool or interesting enough to feel like it is worth the time. I don't know why there are so many good reviews. It really isn't that great of a game.
