This is horrible.
I hate to say it, honestly, but it was horrible. The only part of this that looked like any effort was put ino it was the first person bit. The rest just looked like you put no effort into it, just did it in like five minutes. And it was pretty much the same thing: Samus would fire, run, trip, Metroids would attack her, she'd go into Morph Ball mode, lay a Morph Ball Bomb, it would detonate, next scene, same thing. It needs more variety, and the artwork could use a bit of improvement. I respect you for trying, but you could have tried a lot harder, I'm sure.
