For the first puzzle, follow the green line from left to right and turn all the knobs to go with the flow (dont forget the little one) the light will go green so you can click the "open door" switch!!
it must be something to do with the code/ads on this page...as it works fine elsewhere/newgrounds/mousebreaker etc!!
I'll leave it on over night but if its still having problems tomorrow I'll remove it and my other games!!
Could you try it on www.mousebreaker.com??
it could be something to do with the ads/chat/etc on this site as I'm not having reports of problems elsewhere!!
Not sure why...its worked many thousands of others over the past couple of weeks!!
Have you tried viewing it on a different browser? What browser/OS are you using??
walkthrough added to my site (see my profile)
The safe is very possible and thousands of others have done it, try moving the mouse pointer further away from the dial, its much more accurate then!!
eating pies and mints to top-up your health (at the best time not straight away) is a good idea to buy more time!!
