Just to clarify for people...
THERE IS A FLUFFING MUTE BUTTON! Click on the picture in the top left, and then drag your mouse to scroll right. There is a mute button people. You just have to get off your asses and find it.
The undo button is virtually useless. If you've already been spotted and you accidentally move another step, there's nothing you can do. You should be able to undo two or three moves.
Yes! Completed the game! Although I think it had a bad effect on my social life, since whenever I see a puzzle I now have a nervous breakdown. Good game though!
