I was interested into how complicated this seemed to be. It just seemed to be too hard of a game. I then realized you had to crotch down to shoot your weapon. That was weird, but at least I understood it. This is for the most part a standard game. It won't be one I'm going to complete.
It is worth checking out to see where it goes. It's fairly short, but most games here are like that. I had to congradulate myself on getting the secret medal! Then again, it's so easy anyone should figure it out. It has nothing to do with the cutscenes, so skip them.
