Entry for Ludum Dare 28: "You Only Get One"

You are lost in a foggy maze inhabited by a malicious wraith. All you have to defend yourself with is your pistol, and you only have one bullet for it. To win, you must either find your way out of the maze, or kill the wraith. He will often send shadows at you to confuse you, so you must be careful to shoot ONLY the real wraith. If you fail to land your bullet, your only hope is to make it out of the maze.
