"Coma" is a flash game on Newgrounds. It was created by a guy named Thomas Brush (wittyhobos), and it is actually a pretty neat experience.

I played through it twice already. It's not a long game at all. My second time playing it took me like ten minutes to complete it, but I did have a bit of trouble on my first playthrough.
