Change just one thing...
I think that you should change the story, I personally have no problem with it, but others do and its lowering your score and thats just gay. Your not a racist as there were white, black, yellow, and no doubt fucking green people there :P. Change the crane to a corsor is a good idea, pretty easy to do as well, and would make the game a little better.
And why the fuck is it called X-ray?!? I was expecting some kind of messed up porn thing.
Good work and make another, you need more deaths and other shit work on it and it will be more badass than it already is.
