Undo Last Move/Shot

Takes back the last move or shot. You can press undo all the way back to the beginning of the level if you want. If you are playing the game and you select Restart , you can also Undo the Restart command. This is good for checking to see how the level looked before you started it. If you press any key after a "Restart Undo" the undo buffer will be reset and you will not be able to undo it.
