Had the same thing happen to me as someone previous. As I was traveling around... first I lost my eye then the background went all grey. Could not play past that.
Was an interesting game but as another person reported, shortly after getting the zero gravity thing, all the background turned Grey, and all I could see was my character, and i could no longer navigate the game.
I'm not exactly sure what I just played, I didn't get through all the rooms, I'm not sure if I got all the abilities, and I never found the family, all I found was the dead guy; I'm guessing this game had to do with being the only survivor of a war that your were meant to be in, being the first to have the "super soldier" thingy tested on. Pretty damn good.
It's amazing, and it gave me chills as I played through it. I also love the message you incorporated into this, war never does good to anyone in the long run, for the winning side or the losing. The story is also terribly sad, but amazing. Five stars. You and the game deserve it.
One of the most incredible games on the internet.
